IVE Rei Is Miseki Seoul’s Brand Ambassador for 26 Spring/Summer

Rei (레이) of IVE (아이브) has been named the brand ambassador for Miseki Seoul (미세키서울), the Korean fashion label building its identity around a fictional Japanese designer. The announcement dropped on March 6, 2026, and the pairing makes more sense the deeper you look at it.

Why Rei and Miseki Seoul Make Sense

Miseki Seoul launched in 2023 with an unusual premise: the brand narrative centers on a “virtual Japanese designer” named Miseki Rei, whose imagined aesthetic shapes every collection. Monochrome palettes anchored in black, white, and gray. Asymmetric, off-balance construction details. A brand philosophy that prioritizes the feeling of excitement over the product itself. That story now has a real face, and she happens to be Japanese.

For Rei, the Miseki Seoul deal lands at the right moment. The 22-year-old has been building a fashion profile that few fourth-generation idols can match right now. In January 2026, she and IVE bandmate Liz became brand ambassadors for Maison Valentino, attending the haute couture week show in Paris. The Miseki Seoul campaign continues that momentum, now bringing her into a Korean brand story that was already written with her in mind, even before she was attached to it.

The Brand Behind the Collaboration

Miseki Seoul is a relatively young label, but it has moved quickly. The brand opened its first offline flagship in Hannam-dong, Seoul, a neighborhood that has become a proving ground for Korean designer brands looking to attract both local and international shoppers. Foreign visitor traffic at the store is already significant enough that Japan has been identified as the brand’s primary overseas expansion market, with dedicated social media operations, pop-up events, and collaborations in the pipeline.

A representative for Miseki Seoul said the label expects the Rei partnership to have a positive impact on its future direction, citing the alignment between the brand’s Japanese emotional aesthetic and Rei’s image. The 26 SS collection focuses on the label’s signature monochrome-based styling and unbalanced construction details, which Rei will carry naturally.

Rei’s Fashion Trajectory

Born Naoi Rei in Nagoya, Aichi, Japan, Rei trained under Starship Entertainment for roughly three and a half years before IVE debuted in December 2021. She has since emerged as the group’s standout in the fashion space. Beyond Valentino, she holds ambassador roles with Luna makeup (Korea and Japan markets), rom’u contact lenses as Japanese muse, and Millet outdoor. She also appeared in a campaign for Pokemon Card Game Pocket alongside IVE member An Yujin.

Her pop culture moment of the past year came from IVE’s “ATTITUDE” era. The “Pokju Ggini” challenge, a rampaging guinea pig dance move from the track, accumulated over 38.6 million TikTok views and earned Rei the Best Trend Leader award at the TikTok Awards Korea 2025 in October.

The Bigger Picture

The Rei and Miseki Seoul pairing reflects a broader pattern in K-fashion: emerging Korean labels are increasingly leaning on Japanese idols to accelerate their reach into Japan, the most accessible major overseas market for Korean brands. Rei’s background, combined with her already substantial following in Japan, makes her an efficient bridge for a brand actively targeting that audience.

IVE as a group has also established itself as a fashion-forward act, with multiple members holding brand deals at the premium and luxury level. Jang Wonyoung has fronted Tommy Hilfiger campaigns, while Liz’s Valentino and domestic brand commitments run alongside Rei’s expanding portfolio. Miseki Seoul adds another data point to that story.
