Kep1er's fashion partnership was expected to give the K-pop group another campaign in Japan. Instead, its appointment as SHEIN's 2026 brand ambassador has prompted criticism from some fans, who question why the six-member group is promoting a retailer scrutinised over its fast-fashion business model and environmental claims.
Announced on 11 November 2026, the collaboration includes campaign images, promotional videos and activities across Japan. Titled #SHEINxKep1er, it features the members modelling autumn and winter trends, with advertising planned for Shibuya, Umeda and Shin-Okubo. A temporary exhibition at SHEIN's Tokyo showroom in Harajuku is also included. The announcement gives the retailer a route to reach K-pop followers through a group with an existing profile in Japan, while offering Kep1er another opportunity to appear in a large-scale fashion promotion locally.
Some social media users have questioned the group's decision to work with the retailer, arguing that the partnership could affect its public image.
Why Kep1er's SHEIN Partnership Is Dividing Fans
The criticism gained attention after a post describing the partnership as one of the most unexpected jobs for a K-pop group attracted more than 2.2 million views, according to Japanese outlet RBB TODAY. The report also highlighted comments questioning why Kep1er had chosen to promote SHEIN, with some users describing the collaboration as disappointing. These reactions do not establish that the entire fandom opposes the deal.
SHEIN's fast-fashion business model has attracted scrutiny from consumer organisations and regulators, particularly over environmental marketing and consumer protection. In May 2025, the European Commission's Consumer Protection Cooperation Network notified SHEIN of practices it considered potentially contrary to EU consumer law. Concerns included misleading discounts, pressure-selling tactics and incomplete or misleading information about consumers' rights. The notification formed part of a consumer-protection process and should not be confused with a final court judgment.
In August 2025, Italy's Competition Authority announced a €1 million (£835,000) fine against Infinite Styles Services Co. Ltd, the company managing SHEIN's product trading websites in Europe. The penalty concerned misleading environmental claims used to promote SHEIN-branded clothing, including statements about recyclability and sustainability. These regulatory actions help explain why the retailer's name can generate criticism beyond discussions about price and trends.
What the Campaign Includes
SHEIN's announcement describes six promotional initiatives under the theme #私をランウェイへ, translated as #ToTheRunway. They include a trend catalogue featuring Kep1er members, outdoor advertising in Shibuya, Umeda and Shin-Okubo, and a limited-time pop-up at the SHEIN TOKYO SHOWROOM in Harajuku.
The activities also include special coupons and a giveaway featuring signed merchandise. Published promotional terms schedule the campaign to run through 6 December 2026.
The Wider Challenge of Celebrity Brand Partnerships
Kep1er's SHEIN collaboration illustrates how endorsements can become conversations about corporate reputation, as audiences consider the retailer's business practices alongside the campaign itself. For entertainment agencies, choosing brand partners involves more than reach and promotional opportunities. Fans may weigh a company's environmental record, labour practices and public controversies, placing performers at the centre of debates about commercial decisions.
The criticism does not establish that the partnership has harmed Kep1er's popularity or commercial prospects, or that the members are responsible for the retailer's business practices. For now, the debate reflects a tension between the commercial appeal of fast-fashion partnerships and growing scrutiny of the industry. The campaign may deliver visibility in Japan, but winning the approval of the group's supporters is a different challenge.
