Upon its release, Perfect Velvet received favorable reviews both domestically and internationally for showcasing the group's ability to switch between their two concepts, their maturity and experimentation as artists, and for breaking stereotypes among South Korean idols in general. The album debuted at number two on the Gaon Album Chart and peaked atop the Billboard World Album Chart, extending their record as the K-pop girl group with the most number-one albums on the latter chart with four. The Perfect Red Velvet became their seventh chart-topper on the Gaon.
Two singles were released from Perfect Velvet: "Peek-a-Boo", and "Bad Boy" from its reissue. Both singles were a commercial success for the group, peaking at number two on both the Gaon Digital Chart and Billboard World Digital Songs, with the latter single becoming the group's first single to receive a Platinum certificate by KMCA. Furthermore, "Bad Boy" went on to enter at number eighty-seven on the Canadian Hot 100 chart, making Red Velvet only the seventh K-pop artist and the third female act to appear on the chart. To promote the album, the group performed on several South Korean music programs such as Music Bank, and Inkigayo, further embarking on their second and third concert tour, Redmare and La Rouge in between 2018 and 2020.
Perfect Velvet was eventually included in several year-end lists from critics, most notably chosen as one of the "Greatest K-pop Albums of the 2010s" by Billboard magazine. It also earned the group several year-end music award nominations, including the Best Pop Album category at Korean Music Awards and Album of the Year category at the 2018 Mnet Asian Music Awards ceremony. A landmark performance by the group was held in North Korea where they performed "Bad Boy" at the "Spring is Coming" concert, to an audience that included leader Kim Jong-un.
Background
Perfect Velvet
On October 30, 2017, news about the group's upcoming comeback appeared on various South Korean news sites, which was then confirmed later that day by their company, SM Entertainment.[4] At midnight on November 8, 2017, S.M. Entertainment revealed the title of the group's new single, "Peek-a-Boo", through a teaser along with the title of their second full album, Perfect Velvet, its release date, and that it would contain nine tracks.[5] The title references the "velvet" half of the group's concept which stems from the meaning behind their name, where "red" is their vivid and bold image while "velvet" stands for their softer and more mature side. These two sides reflect the songs they release.[6] In an interview with X Sports News on November 8, S.M. Entertainment stated that they intend to show "an upgraded version" of the group's "velvet" concept.[7]
The group admitted to being unnerved by the success of their last single, "Red Flavor", as they were preparing for the album which the members participated in making through song selection. Similar to their company's statement, their leader Irene told Billboard that unlike their past two releases earlier in the same year which had been bright, falling under their "red" concept, they wanted to show an upgraded version of what they can show of their "velvet" image. Despite their concerns about the drastic change from their previous comeback, member Wendy stated that she thought it was "good timing" for the album to be released before the year ended as it "can show the perfect Red Velvet performances and songs".[8]
The Perfect Red Velvet
In an interview with Idolator on January 16, 2018 about being nominated at the Grammy awards and working with K-pop artists, American production team, The Stereotypes, revealed they had "a new one coming that's gonna be really cool" when asked about working with Red Velvet. Previously, they also produced two tracks from Perfect Velvet ("Kingdom Come" and "Attaboy"). It was eventually reported that the new song will be the album's lead single, "Bad Boy".[9] Only two months after the release of Perfect Velvet, S.M. Entertainment announced through an image teaser posted on their official Twitter and Instagram accounts on January 23, 2018 that Red Velvet will be releasing a repackage of the album titled The Perfect Red Velvet with "Bad Boy" as its lead single.[10][11] "Bad Boy" was described as a song with a "sexy" or "girl crush" concept by South Korean news sites, which has never been done before by the group. On January 24, 2018, it was reported that the repackage of Perfect Velvet will be released on January 29 with three new songs, including "Bad Boy".[12][13]
On January 26, individual teasers of members Wendy and Joy were released through the group's official SNS accounts which were noted by Kang Seo-jung of Osen as having the vibe of a powerful "eonni". In the same article, Kang also spoke of how their latest concept differs from the group's past releases. These teasers were followed by clips of Irene and Yeri on the following day, with Seulgi's being released on January 28.[14] The reissue was ultimately released on January 29, 2018, at 6PM KST both digitally and physically. The physical album was released in two formats-CD and Kihno kit.

The album's first track, "Peek-a-Boo", was described as an up-tempo pop song with addictive hooks.[15] Tamar Herman of Billboard stated that it is "laden with trop house elements underneath the overarching quirky pop vibe, and is driven by a deep bass drumline, scratchy synths, and metallic beats" which also features "a variety of diverse, playful instrumental elements nestled beneath the main melody". Lyrically, it compares a new romantic relationship to a game that children play.[16]
"Look" (Korean: 봐) is a disco-styled dance song written by Jinbo and Sumin who also composed the song along with Charli Taft and Daniel "Obi" Klein who have written several songs for the group since their first EP, Ice Cream Cake, including the single "Automatic".[17] "I Just" is a pop song with a futuristic bass and distinctive synth sound composed by Aventurina King, Kim Boo-min, John Fulford with arrangement by South Korean EDM artist and DJ, Hitchhiker and its Korean lyrics written by Kim Boo-min.[18] "I Just"'s lyrics express the empty emotions felt after a break-up.[19] The fourth track, "Kingdom Come", has been noted as an R&B song with a gentle beat and a soft melody.

Perfect Velvet received positive reviews from both domestic and international critics. The release of the album was also seen as the group's softer, more mature and sophisticated "velvet" side finally being accepted by the public.[49] Seon Mi-kyung of Osen considered the transition from their last song, "Red Flavor", to their "velvet" concept a bold move, especially when they had just gained notable success and recognition for it, but commented that it is noteworthy the group chose to change their identity and color to showcase their growth as artists.[50] In their review of the album, KookMin Ilbo complimented the songs on the album as "colorful and solid". After shedding light on how the distinction between the group's "red" and "velvet" tracks are not as simple as being "dance" vs. "ballad", they claimed that Red Velvet's music is like a signal that people can now "do this kind of music". They also noted that visually, it references mysterious images of classic B-grade movies reminiscent of retro music in the UK.[51] Kim Sang-hwa of Oh My Star on the other hand, called Red Velvet "a force other groups could not begin to imagine" particularly because of how all five members of the group reached new peaks vocal-wise. He also spoke of their musical experimentation and "future-oriented sound", asserting that it is their strongest ever. He then concluded that the album is one of the most outstanding domestic music records released in the year.[52] Writing for OhmyNews, Oh Joon-young discussed the prejudice that idols are not considered artists and how Red Velvet pushed the boundaries of what idol music should be with their diverse musical inspirations and styles, thus gaining the public's respect.[53] South Korean online magazine weiv also chose Perfect Velvet as their pick for the best domestic album of the year and was the only album by an idol group to be included on the list.[54] In January 2018, Perfect Velvet was chosen by Idology out of 729 Korean albums as the best album of 2017, where 11 of their writers voted.[55]
Tamar Herman of Billboard labelled the lead single as a "stylistic follow-up" to their 2015 single, "Ice Cream Cake", which according to her had the same "haunting, chromatic melody and taunting choral hook". She then described the album as "a lush retro-pop soundscape that offers up a complete turnabout from the vibrant sound and styling of their summer hit "Red Flavor" and The Red Summer".[16] In December, Herman chose it as one of Billboard's 20 Best K-pop Albums of 2017: Critics' Picks.[56] Aubree Stamper of The Michigan Journal stated that "all nine tracks on the album fit well together" and showed a new side of the group.[57] Chase McMullen of The 405 believed that too often than not, most of South Korea's popular girl groups were limited to two concepts, which are "cute" and "sexy" but "Red Velvet's only true interest appears to be dodging what's expected" and is a group who valued their versatility. He also stated that "The album plays like something of a challenge, constantly seeking to top itself". Lastly, he maintained that the members continue to challenge themselves, all the while crafting "irresistible pop that doesn't lose an ounce of sheen once the buzz wears off".[58]

The Perfect Red Velvet
Tamar Herman of Billboard called the title track "Bad Boy" their "darkest yet", comparing them to the rainbow hues of their last single, "Peek-a-Boo", and stated the members "played up their smoother retro leanings" with the addition of the new songs. Herman also commented on the members' styling, noting the "sexy uniforms and athleisure fishnet-and-leather outfits" which depicted the group as "femme fatales". The song's choreography was also seen as the sexiest the group has ever done. Lastly, she called the song and the album "overall representatives" of the group's "velvet" side (a reference to the group's dual concept), contrasting the quirkier "red" songs the group has released in the previous year.[60] Similarly, Ela Teodosio of Christian Today believed that the single was their "most fiery track yet" and stated that the two other tracks that were added to the album "follow the group's theme of retro disco".[61] Avery Thompson of Hollywood Life called the members "the epitome of girl power" as she praised the music video of the lead single.[62] Fuse's Jeff Benjamin opined that the group put their own spin on modern R&B and hip hop, comparing it to the likes of Rihanna, Tinashe, and Cardi B where they incorporate "sassy, catch phrases into their verses and choruses". He then described the other track "All Right" as a "synth-pop cut" and "Time to Love" a "snappy ballad".[63] Forbes stated that The Stereotypes' work on the album "have helped hone the girl group's lush contemporary R&B-meets-pop sound".[64] In December 2018, Billboard included the title track "Bad Boy" in their '100 Best Songs of 2018: Critics' Picks' list while MTV picked "All Right" as one of the 'Best K-Pop B-Sides of 2018'.[65][66] The Perfect Red Velvet was also included in Refinery29's '12 Best K-Pop Albums of 2018'.[67]
In South Korea, X Sports News called "Bad Boy" the perfect blend of the group's intense "red" side and soft "velvet" in their review of Red Velvet's dual concept "red" and velvet" since their debut with "Happiness" and "Be Natural".[68]
Commercial performance
Domestically, Perfect Velvet was a commercial success, peaking at number two on the Gaon Album Chart upon its release.

With over 2,000 copies sold in its first week, Perfect Velvet earned their best US sales week at the time, later surpassed by the group's fifth extended play RBB in the same year.[76] Following the release of the album, Red Velvet appeared on the Billboard Social 50 chart at number thirty-three, a new peak for the group.[77] In Japan, the album debuted on Oricon Weekly Albums chart at number twenty with 2,867 copies, the group's first release to enter the top twenty.
