Which band recorded the 2014 UK Singles chart-topper "She Looks So Perfect"?

5 Seconds of Summer recorded the 2014 UK Singles Chart-topper “She Looks So Perfect.” The song was the Australian pop-rock band’s breakthrough single and became their first UK number-one hit.

Released in early 2014, “She Looks So Perfect” introduced the group’s upbeat blend of pop, rock, and punk-influenced hooks to a worldwide audience. The band—Luke Hemmings, Michael Clifford, Calum Hood, and Ashton Irwin—had already built a large online following before the single’s release, helped by touring as an opening act for One Direction.

The song’s success was notable because 5 Seconds of Summer were often marketed alongside pop acts, yet their music used live-band instrumentation and a guitar-driven sound. The title and lyrics are sometimes remembered as a conventional teen-pop romance, but the track’s identity also comes from its playful, energetic production and instantly recognizable chorus. It topped charts in several countries and helped establish the band before their self-titled debut album arrived later in 2014.
