MUSINSA Collaborates with 'X THE LEAGUE,' Featuring 3 Japanese Creators Competing Globally — Target Brand Records 7x Year-on-Year Sales on Launch Day

South Korea's leading fashion platform, MUSINSA, announced that during its ongoing summer global sale 'MUSINSA MONSTER SALE' (June 14 (Sun) to June 24 (Wed), 2026), its collaboration with the global commerce league program 'X THE LEAGUE' led to the target brand 'MUSINSA STANDARD WOMAN' achieving first-day transaction value seven times higher than the same period last year. Furthermore, overall sale transaction value surged 486% year-on-year during the first three days of the event.

This strong performance stems from combining the inherent appeal of Korean fashion brands with the unique sensibilities and styling expertise of Japanese creators, making Korean fashion more accessible and relatable to Japanese customers. Additionally, the campaign succeeded in delivering an engaging, participatory shopping experience—where fans can support their favorite creators through purchases—contributing significantly to the strong initial response.
