Girls’ Generation’s stylist caps K-pop fashion industry over years
Stylist Seo Soo-kyung talks about her career and the structural problems in the K-pop fashion business

Having been involved in the industry for almost 15 years, Seo has witnessed how K-pop fashion has transformed over the years. Crediting Big Bang for K-pop fashion’s ongoing worldwide fame, Seo said the boy band was among the pioneers to feature a more down-to-earth approach to fashion. The group’s wardrobe was as realistic and hip as street fashion in Harajuku — and easily accessible to the public as well.
“Before Big Bang, K-pop artists’ costumes were literally costumes. Stylists’ job was to kind of copy the lines of famous designers and recreate them into stage outfits. But Big Bang members were different in that they actually wore outfits freshly out from a designer’s collection. The public could also dress like Big Bang. From that point on, K-pop stars like 2NE1 and BTS started to wear collections,” Seo said.
