Last updated: October 12, 2026. CORTIS’s brand partnerships include group campaigns and entertainment collaborations, while individual members have also appeared at major fashion events and in brand-related editorials. This guide separates confirmed partnerships from fashion appearances so readers can tell which activities are officially announced ambassador roles and which are not.
For the group’s lineup and member information, visit the CORTIS members profile. You can also explore CORTIS news, CORTIS comebacks and releases, and the CORTIS discography.
CORTIS Brand Ambassador and Partnership List
As of October 12, 2026, the confirmed public partnerships listed below should not all be described as ambassador appointments. The NBA officially named CORTIS to its “Friends of the NBA” program, and Vans has featured all five members in a brand campaign. Neither announcement, by itself, means every member holds a formal global brand-ambassador title.
| Brand or organization | Member(s) | Confirmed relationship | Announcement / source |
|---|---|---|---|
| Vans / ABC-MART | All five members | Featured group campaign for Vans footwear. The second “Oh, What Fun” campaign launched in Japan on October 9, 2026. | ABC-MART campaign announcement |
| NBA | All five members | Named to the NBA’s “Friends of the NBA” celebrity and influencer program in Asia, with planned event appearances, original content, promotional activities, and co-developed merchandise. | Official NBA announcement |
1. Vans: Group Campaign Featuring All Five Members
Vans has featured MARTIN, JAMES, JUHOON, SEONGHYEON, and KEONHO in its “Oh, What Fun” campaign in Japan through ABC-MART. The second campaign launched on October 9, 2026, and showcases the five members in autumn and winter styling with Vans footwear, including classic models such as Old Skool and Authentic.
This is a confirmed group campaign and brand collaboration. Unless Vans or the members’ agency announces an ambassador appointment, it is more accurate to call CORTIS the featured artists in a Vans campaign rather than describe each member as an official Vans global ambassador.

2. NBA: “Friends of the NBA” Partnership
On January 18, 2026, the NBA and BIGHIT MUSIC announced that CORTIS had joined “Friends of the NBA,” a program for celebrities and influencers across Asia-Pacific. The NBA said the collaboration would involve games and events, original content, promotional activities, and the development of NBA-branded apparel and merchandise.
This is an officially announced partnership with the basketball league, not a fashion-house ambassadorship. The NBA’s own announcement is the primary source for the program’s scope.

Individual Members: Fashion Shows, Editorials and Brand Appearances
CORTIS members have also attracted attention through fashion-week invitations and magazine editorials. These appearances are relevant to the group’s fashion profile, but attendance at a show, wearing a designer’s clothing, or appearing in an editorial does not automatically confirm an ambassador contract.
MARTIN
MARTIN has attended a Saint Laurent show in Paris. His attendance is a fashion appearance, not by itself confirmation that he is a Saint Laurent ambassador. Read more on the MARTIN profile.
JAMES
JAMES appeared in Vogue Korea’s “Vogue Man” feature, with Prada clothing credited in the editorial. The feature does not confirm that he is a Prada ambassador. See the JAMES profile and KWaveHub’s report on his Vogue Korea feature.
JUHOON
JUHOON attended Dior’s Spring/Summer 2027 menswear show in Paris alongside fellow CORTIS members. This is a documented fashion-week appearance; it should not be presented as a formal Dior ambassador appointment unless an official announcement confirms one. Visit the JUHOON profile.
SEONGHYEON
SEONGHYEON attended Dior’s menswear show and appeared in a Vogue Korea digital-cover feature associated with Louis Vuitton. These activities are fashion and editorial coverage, not proof of an official Dior or Louis Vuitton ambassadorship. Read the SEONGHYEON profile and KWaveHub’s Louis Vuitton editorial report.
KEONHO
KEONHO has been covered by KWaveHub for his attendance at a Chanel show during Paris Fashion Week. Attendance at a fashion show does not itself establish that he is a Chanel ambassador. See the KEONHO profile and the report on his Chanel show invitation.
Are CORTIS Members Official Brand Ambassadors?
Brand relationships can take several forms: a formal ambassador appointment, a campaign featuring an artist, an event invitation, a magazine editorial, or a broader promotional partnership. These categories should not be treated as interchangeable. As of October 12, 2026, the primary sources cited in this article confirm CORTIS’s Vans campaign and NBA “Friends of the NBA” partnership. The fashion appearances listed above are not described here as formal ambassador appointments because the cited coverage does not establish that status.
