You Must Be Cold

A woman is cold for some reason. Male character takes off his coat and gives it to her, resulting in her going around for some scenes in a men's suit jacket or leather coat and not much else.

Usually plays into the Double Standard because the coat-giver is (almost) Always Male and the coat-receiver is (almost) Always Female; only female characters tend to get skimpily clothed enough to need it, and men have to look after women. In fact, about the only time the characters are not a romantically linked male and female one of them will be a child, child-like, sick or otherwise vulnerable, because it's about taking care of the other person. Variations (female-male, male-male, female-female) are becoming more common.

Somewhat Truth in Television: The more muscle mass people have, the warmer they feel, since muscles burn energy even if people aren't active. Since men have on average 50% more muscle mass than women have, they also should feel less cold. There's also the fact that the man is normally larger overall in these situations, so the woman's jacket wouldn't necessarily fit, giving her less reason to offer it to him.

Straight examples

Anime and Manga

Arisa: Tsubasa gets a jacket from Manabe when they're both stuck on the mountain. He also says Take Off Your Clothes.
Kurama gives Nana his suit jacket in Elfen Lied, although this has less to do with chills and more to do with preserving her modesty.
On Outlaw Star, Gene offers his cloak to Melfina after getting her out of her box. Of course, in this case, it wasn't so much that she was cold as it was that they couldn't exactly have a completely naked woman running around with them and still remain inconspicuous.
In Tengen Toppa Gurren Lagann, Simon wraps Nia in his Badass Longcoat after rescuing her from Anti-Spiral. Doubles as a Shirtless Scene and triples as a rare male Of Corsets Sexy for Simon.
Lelouch gives his Zero cape to Euphemia in the island episode of Code Geass while her clothes dry out. Later, in R2, Lelouch gives his jacket to his personal Action Girl Kallen, who has been running around in a Playboy Bunny suit since the beginning of the season. Certain shippers went Squee.
In the first episode of Hayate the Combat Butler, Hayate gives his jacket to Nagi when she's freezing. Subverted in chapter 262: Athena tells Hayate she's cold, and he offers her his jacket, completely oblivious to her subtext - she wants him to give her a cuddle. He catches on eventually.
- Although not quite implied that it's because she's cold, Hinagiku is seen wearing a male's (possibly Hayate's) jacket as she runs from the beach where she's just played beach volleyball, so she's in a bikini.
In Beauty Pop Kiri spills coffee on her sweater on a chilly day and Narumi gives her his heavy uniform jacket on the way home.
In Digimon Frontier Kouji gives his coat to Izumi in an episode where they are going through a snow field. It feels more like Ship Tease than actual romantic involvement, though.
One Piece:
- A running gag in the series consists of someone asking Chopper for his coat, and him reminding them that it isn't a coat.
- In a cover page arc, Kalifa is seen to be wearing Jyabura's shirt in place of the dress that was torn up in a fight after first having draped herself in a blanket. Whether he gave it to her or she took it from him is left unexplained.
- After Ace's death, there is a scene where the other members of the crew find out; Robin, who is in a snowy area, is offered a coat by a soldier.
Played with multiple variations in Gantz: Kishimoto wakes up teleported into Gantz' pre-game apartment naked for her introductory full-frontal fanservice. Kurono stares transfixed (and in breast-shock) and lovestruck (or lust-struck), but makes no move to offer his coat. Kato, the chivalrous one, has no coat so orders Kurono to offer his.
In Fullmetal Alchemist after Winry has a breakdown because she can't shoot Scar, the murderer of her parents Edward gently places his coat around her shoulders because she is suffering from shock and still shaking. Uncommonly this one could be viewed as s completely platonic example even though they become the Official Couple
In Full Metal Panic!, Sousuke lends Kaname his jacket after he rescues her from being kidnapped. In this case it's less of a "lend" and more of a "there's no chance in hell I'm going out there with nothing but a paper gown on, so hand that jacket over or I'll smack you."
Negi in Mahou Sensei Negima once did this late in the School Field Trip arc with Asuna after her 'encounter' with Fate, handing her a towel (this scene was one of the first clues of the series' move into the dramatic). Played differently when Chisame was magically aged-down with over-sized clothes, causing Negi to give her his coat.
- Inverted far earlier in the series, when Asuna gives her jacket to Negi during the library arc.
In Scrapped Princess, Chris Armalite gave his captive Winnia Chester his cape because she's cold, while they await Shannon's arrival in an early episode.
In the Soul Eater manga, Marie once teased Joe's tendency to dress lightly, saying he wouldn't be able to perform this trope. Oblivious to her joke, he promptly ripped off his shirt and used that instead.
Rare female/female example: Motoko gives her cloak to Shinobu after her sword technique shreds Shinobu's clothes in Love Hina. Take that as you will.
Another female/female example from Claymore: Clare gives her cape to Jean after Jean nearly awakens and is naked.
Not really a case of temperature, but in Tokyo Mew Mew: a la Mode, Tasuku sneaks Berri out of her school for a day of fun playing hookie. Berri says that people will notice she's wearing her school uniform, so Tasuku just gives her his hoodie jacket to wear.
In the Detective Conan Non-Serial Movie The Phantom of Baker Street, this occurs as a three-fold maneuver. Ayumi shivers, so Conan gives her his blazer, then Mitsuhiko realizes that, as a guy, he needs to do something similar, and gives his jacket to Haibara Ai, then Genta, not wishing to be the only guy not doing this, gives his jacket to Ran.
- As Genta was the only boy who was big enough for his jacket to fit Ran, this made a good bit of sense, even if it was coincidence. Also, Mitsuhiko likes both Ai and Ayumi, Ayumi likes Conan, and Conan (Shinichi) likes Ran, so...
Inuyasha finds an excuse to give Kagome his fire-rat cloak every once in a while. The cloak is magically fire-proof and knife-proof, so the trope can be played straight even when Kagome is fully dressed.
- Inuyasha gives Kagome his kimono repeatedly over the course of the show, but never because she was cold - the kimono functions as armor, so usually he gives it to her as protection, although he did give it to her once when her clothes had been stolen.
Yu-Gi-Oh!: Yugi does this for Anzu/Téa when they're trapped in the Arctic-like sector of Noa's virtual world. The two blush and turn shy for a few seconds.
- And a non-romantic version when Kaiba drapes his trenchcoat over the sleeping Mokuba.
Miyako and Will from Private Prince invoke this when they get reconciled after having broken up. Justified Trope as Will's clothes has been soaked with cold water after Miyako's Almighty Mom went Mama Bear on him.
The first Ghost in the Shell movie has Batou draping his jacket over the shoulders of his partner, Major Kusanagi, after the fight in the shallow pool with a ghost-hacked perp, which she used her thermoptic camouflage for (which in the context of this movie meant that she was practically naked).
- In Innocence, Batou silently gives his jacket to the Sex Bot that Motoko's consciousness is currently inhabiting, and she accepts with a minor comment. This serves as a meaningful Call Back to the first movie, but it also serves the purpose of allowing the viewer to easily distinguish Motoko from the dozens of identical gynoids in the scene.
Crusher Joe has a rare female to female (from male) version. Joe and Alfin have finally located the MacGuffin Girl, who's been in cold-sleep the whole movie. While Joe gives cover fire, Alfin picks up the girl, after first liberating a lab coat ("Give me that you pervert!") from one of the doctors.
In chapter 10 of the Uragiri wa Boku no Namae wo Shitteiru manga in one of the many Ho Yay moments they have Luka puts his jacket on Yuki.
In episode 95 of Fairy Tail, Natsu gives Lucy his cloak when everybody get caught in the rain.
In the Saint Beast OVAs, Judas gives his cloak away twice. Once to Shin in the typical fashion, and the other time to Pandora after saving him from an Attempted Rape because he had Clothing Damage of the shameful kind.

Fan Works

In The Green Hornet fanfic Bad Medicine, the Green Hornet notices that the narrator is shaking from both cold and shock she had just killed the man who had abducted and tortured her in self defense and, like the gentleman he is, drapes his trademark green overcoat over her shoulders.
In the Kaichou wa Maid-sama fanfic Seduction, Tora gives Sarakshi his coat after he sees her shiver from the cold while standing in the window.

Films -- Live-Action

Tremors. When the two male heroes and the heroine are trapped overnight on some rocks by the graboids, one of the male heroes gives his coat to the heroine.
- If you watch the scene carefully, it's actually hero #2 who gives her hero #1's coat; he's playing matchmaker for her and hero #1.
In Quantum of Solace, James gives his jacket to Cami when they're stuck in an underground pit and she's in a skimpy Little Black Dress.
Cal gives his coat to Rose in Titanic (justified since it was night in the middle of the North Atlantic in April and she'd been slogging through freezing seawater). Unfortunately, he forgot he put the Heart of the Ocean in it...
In Under the Rainbow, Chevy Chase's character gives his suit jacket to Carrie Fisher's (very scantily-clad) character when they get Locked in a Freezer.
One of the few tropes played straight and serious in Spaceballs, with Lone Starr offering his jacket to Vespa. She asks if he will be cold, and he replies that cold never bothers him. Then he shivers.
John Dillinger does this twice in Public Enemies. The first time he gives a bank teller the gang abducted as a hostage his coat and hat just before they dump her in the countryside. The second time he gives Billie his coat when they leave the dance hall where they met for the first time and she is shivering because her own coat is thin (and cheap).
The Rocketeer: The Big Bad has captured the Love Interest and is taking her to his Global Airship in the middle of the night. He asks her if she's cold. She says no. He asks if she's sure. She turns her head in disgust.
- It also doubles as a Crowning Moment of Awesome for Jenny, the Love Interest, as she's in a pretty hopeless situation and still manages to give the villain a pretty big damn you to Hell. Her response when the Big Bad offers the coat?

Jenny: I'd rather freeze.

- But then Double Subverted:

Big Bad: [smirk] "You know, I prefer you that way."

She then takes the coat.

Played innocently in 1958's Horror of Dracula, where Van Helsing gives his coat to a scared little girl, and then tells her "You look like a teddy bear."
In The Net, Angela and Devlin are walking down a beach at night, and noticing that Angela is cold, Devlin wraps a sash around her bared midriff. This is of course all part of Devlin's ploy to steal the disk that Angela has come into posession of, and then kill her.
In Wizards of Waverly Place: The Movie, Justin offers his jacket to Alex in the infamous campfire scene. Given that they're brother and sister, this only adds to the UST/Relationship Writing Fumble/Brother-Sister Incest their relationship is built on.
- A bit of a subversion, as she actually refuses the jacket.
Sherlock Holmes. In A Game of Shadows, Moriarty actually places a fur coat around Holmes' shoulders when he sits down for their chess game. Just another Ho Yay moment in a movie that's full of them...
In the first X-Files movie, Fight the Future, Mulder wraps Scully in his coat after rescuing her from the cyro chamber.
Thor gives Jane his jacket before he storms the SHIELD base, having noticed it may rain.

Literature

An interesting variation occurs in Goth Girl Rising by Barry Lyga. After Fanboy and his mom come to get Kyra from the police station, there's a scene where he comments on how cold she must be, but rather than offering his coat, he gives her his hat. (This makes sense when you remember that she shaved her head earlier in the book.) Leads to a Crowning Moment of Heartwarming later when he tells her that his change in personality was because of her and she says that's even better than him giving her his hat.
In Twilight Edward gives Bella his jacket in a cold restaurant. To be fair, he is waiting for her to go into shock after nearly being raped and it's not like he would notice the cold anyway.
In the Eighth Doctor Adventures novels, the Doctor destroys his home planet and loses his memory. His TARDIS at the time also happens to be a rather unkind young woman named Compassion, and she decides the best solution to the problem is to leave him alone on Earth for over a hundred years. Fitz, his other companion and Heterosexual Life Partner,^[1] puts his leather coat and fedora on the unconscious Doctor before Compassion ditches him.
In King Hereafter by Dorothy Dunnett, Thorfinn gives his cloak to Groa before they go outside—but they're in the middle of The Masochism Tango, and the conversation ends abruptly after she pushes his Berserk Button.
In the beginning of The Girl Who Circumnavigated Fairyland in a Ship of Her Own Making by Catherynne M Valente, The heroine, September, is given a velvet smoking jacket by a Green Wind in the form of a fine gentleman. The jacket is very eager to please and fits her immediately. Throughout the course of the story it becomes various things, mainly waterproofing for the titular ship, and lengthens into a dress when September loses hers.
Found, of all places, in From Baghdad With Love, a (true) story otherwise about dogs rescued and adopted by American troops in Iraq. The narrator introduces a female war correspondent who forewent niceties such as bedrolls and blankets, sleeping on the bare ground in the same clothes all the time in order to carry more important things like her journalism equipment. He mentions that in her notes she often woke up with a Marine poncho draped over her.
Played with in The Crocodile on the Sandbank, the first Amelia Peabody mystery. Amelia finds a young woman who has fainted in the streets of Rome and is appalled that none of the men nearby have invoked this trope. Amelia proceeds to confiscate the coat of the nearest man (insulting him in the process), and uses it to cover the woman.

Live-Action TV

Buffy the Vampire Slayer: Angel lends Buffy his coat (because she's just the last hope of humanity, she can't be expected to dress herself adequately) and Xander gets pissed, because he knows what it implies.
- Spike also does this for Drusilla in their first appearance. This doesn't make a lot of sense, given that neither of them have body heat.
  - Dude, it's Drusilla. It doesn't have to make sense. It just has to make her happy.
  - It was shown in a later episode of Angel that severely weakened vampires, like ones that haven't drunk blood in a long time, can feel cold.
- Xander (having taken on the personality of a macho soldier due to a spell) does this for Cordelia with his army shirt in "Halloween", foreshadowing their future relationship.
- Subverted when Faith first arrives in Los Angeles and a sleazy looking guy (clearly a pimp) offers his 'protection'. Faith shivers and when the guy is taking off his leather jacket to fulfil this trope she beats him up while his arms are restricted.
Played surprisingly straight in "Chuck vs. the Delorean".
Doctor Who:
- In the Christmas special "The Runaway Bride", the Doctor gives Donna his jacket. She's fully dressed, but since she's wearing a sleeveless wedding gown and it's Christmas... Donna undercuts the attempt at chivalry somewhat by commenting "God you're skinny... this wouldn't fit a rat." Though she has a point.
- Later, in "The Poison Sky", the Doctor gives his coat to hospital gown clad Martha, whose clothes were stolen by her clone.
- In The Vampires of Venice, the Doctor replaces the stripper who was supposed to jump out of a cake at Rory's stag party, and thinks the stripper must be cold.

That reminds me, there's a girl standing outside in a bikini. Could someone let her in and give her a jumper? Lucy. Lovely girl. Diabetic.

The West Wing: Donna comes outside her apartment in the ice and snow in a ballgown, without a coat of course, and Josh immediately drapes his coat around her shoulders.
- In an earlier episode, Donna wears Josh's coat to go outside because it's warmer than hers. He doesn't give it to her in this instance, however; she just takes it and he complains to no avail.
In one episode of Ashes to Ashes, Gene Hunt sees that Alex is shivering and looking unwell. His remedy for that is to wrap her in his coat and drag her downstairs to a bar (resulting in her looking rather ridiculous as she's already wearing her own jacket). Of course, this being Gene, he grabs his coat right back when he's called away.
Happens in an episode of My Three Sons. Steve goes to an office stag dinner, which starts off as a rather dignified affair—until a go-go dancer in a tasselled bikini shows up to entertain the group. The cops show up to put an end to the party, leaving the poor woman unable to obtain her (apparently more decent) street clothes. Steve does the gentlemanly thing and gives her his jacket to cover herself as they escape the party.
In the Sabrina the Teenage Witch episode "Hilda and Zelda: The Teenage Years," Gordie offers his jacket to Aunt Zelda while she is disguised as a fellow teenager. She is cold and takes the gesture at face value, oblivious to the romantic implications of the trope; she's surprised when Gordie later starts making advances on her.
Clark Kent has done this on a few occasions on Smallville thanks to the fact that he almost always wears a jacket. Most rescuees were girls, but one was a little boy who had been aged into a teenager, tearing his clothes.
On Boy Meets World, Cory does this for Topanga at one point. The jacket ends up becoming a minor plot point in that episode.

Music

There's an old song involving a young girl being offered a coat, first by an older man and then by a younger one that she's interested in.

"Are you cold?"
"'Bout to freeze"
"Would you like my coat?"
"Just the sleeves."
"Full or empty?"
"Empty, please" for the former then "Full, please" for the latter.

Videogames

In Star Ocean the Second Story, a Private Action in a snow town involves Ms. Fanservice Celine whining about being cold. Claude tells her she should have put on some clothes and she explains that she cannot use her magic if she covers up her runes (which are on her inner thighs).
After the Christmas Party in Tokimeki Memorial, Mira Kagami comes without a party coat because she's from such a poor household that doesn't have enough money for one, barely being able to afford a dress. After the party, if she's in Tokimeki State with the protagonist, they'll go back to home together and she'll sneeze, prompting the protagonist to give her his coat. She pushes the trope to Comforting Comforter zone by taking his arm put herself close to him, so she can give him some warmth in return. And on top of that, she'll give her his coat back a few days later... with all its little tears sewn off.
Implied in some form in Persona 3 Portable, in the tenth and final scene of Shinjiro Aragaki's Social Link with the female protagonist. After the two of them go out to the shrine at night to talk, Shinjiro admits he'd like to stay out there a little longer, "...but aren't you cold? Hey, c'mere."
In Katawa Shoujo, one of the earliest events in Shizune's route has Hisao putting his school jacket on her as they run errands in a very cold day. Namely, they had betted on carrying a very big box and Shizune lost, so she's carrying it all alone despite Hisao's protest; then it gets cold and Hisao decides to at least do something for her, and puts the jacket on her.

Webcomics

The webcomic No Need for Bushido does this early on in this strip.
In General Protection Fault, Nick gives his coat to Ki while stepping out of their car to discuss their feelings for each other after his "date" with Trudy results in him confessing that he's in love with her. Later, in the "Rendezvous a Paris" arc, Fooker gives his coat to Sharon. In both cases, the female characters are wearing sleeveless dresses.
After the restaurant explodes in "Not A Good Idea" in Sluggy Freelance, Torg gives Sasha his flannel to wear over her dress.
In Questionable Content, Sven gives his sweater to Hannelore during their "date" (she's not actually interested in him, just wanted to see how dates go).

Western Animation

Batman Beyond: Terry gives his coat to Melanie in her first episode. She's still wearing it when they part, but somehow Terry manages to be wearing it in the next scene.

Real Life

Biology actually justifies this trope since women tend to have a lower body temperature than men. Additionally, the size difference means that women generally lose heat more easily due to their surface to volume ratio, and that it's far far more likely the guy's coat will fit the girl than the other way around. Men are also less likely to leave coats at home in the first place in the name of fashion.
- Or to wear a Stripperific outfit in the first place, resulting in being cold regardless of the weather.
