For years, their status has remained relatively unchallenged, but it is difficult for anyone at the top to stay there. EXO also struggles with the perception that they are too perfect, a manufactured pop act without much personality. Korean boy groups also have to deal with the country’s mandatory military enlistment policy, which effectively puts a two-year pause on their careers that is hard to bounce back from. It is one reason why this particular comeback is so crucial for EXO, and why they chose to dramatically change course. “Ko Ko Bop,” the lead single and sole video to be released from The War, is the aesthetic opposite of the band’s previous summer single, “Monster.” Musically, it combines EDM and reggae. It is a sun-soaked song with a distinct “tropical” vibe, and that sharp tonal shift is most clearly communicated through the clothes.

The starting point for the video’s style was The Talented Mr. Ripley, specifically the rich, disaffected Dickie Greenleaf, played by a young Jude Law, as he lazes about the Italian coast. “Ko Ko Bop” reimagines the eight singers (Lay, the group’s only remaining Chinese member, was unable to participate in this album due to his “schedule”) as younger, more fashion-forward versions of Dickie. Sehun wears a Saint Laurent Hawaiian shirt from Spring 2017, covered in retro pop surfboards and station wagons; his hair has been dyed and spiked to resemble a Bird of Paradise. Chanyeol has hair the color of tropical punch and has thrown a white Céline blouse with watercolor blooms over a Saint Laurent logo tee; Baekhyun appears in Valentino, a mustard ikat Etro blazer, and a red mullet. A matching pair of palm tree–dotted All Saints shirts make the rounds on almost all members, loosely swapped around to convey the shoot’s trippy, drug-fueled vacation vibe (a bit odd, considering Korea’s anti-drug culture). All said, it continues EXO’s tradition of slowly pushing the boundaries of K-pop men’s fashion.

The band began honing their singular take on style two years ago with the song, “Call Me Baby.” Before that, they were generally clothed in matching suits or tees plucked off the racks of Boon the Shop and other local boutiques, a one-size-fits-all solution that emphasized their uniformity. In 2015, however, they found a way to bring out each member’s personality by tailoring what they wore in each shoot. More importantly, they began to source designers that K-pop stars were not wearing at the time. Back then, when singers wore high-end fashion, they generally went with big name, easily shoppable brands—Saint Laurent, Louis Vuitton. EXO reached instead for labels fashion people love: Pieces by Raf Simons, Dries Van Noten, archival Helmut Lang. These were mixed with Korean designers, including custom suits from Heich Es Heich, and eventually, a few items from their personal collections—a surprising move. K-pop bands, EXO included, are known for casting off and slipping on new identities with each album. To let a bit of their personal taste shine through, no matter how small, felt like a change.

It is a sartorial mix that has influenced the rest of the industry and reflects the country’s growing emphasis on individual style, which took centerstage on their Exo’rdium world tour, where the above photos were shot. Below, they reflect on the band’s evolution and their own. Kai prefers simple pieces from A.P.C.; D.O., all-black workwear from American heritage brands. Chanyeol is passionate about streetwear—Vetements, Balenciaga, Supreme, Gosha—and he recently confessed to keeping the tags on his clothes for a month, unable to tear them off. Moments like this are thrilling; they feel intimate and authentic, a real flash of expression through fashion. There’s no better way to begin again.
