Picture this: hundreds of young South Koreans milling around a courtyard, dressed in costumes you will probably never see anywhere else in Seoul, or all of South Korea for that matter. Sheer tops, sequined trousers and outerwear so generous in fabric allotment that collectively it could clothe the residents of an entire town. Photographers scream at fashionistas, “Can you look this way once please?” Young mothers drag toddlers in tow, having dressed them in perfectly styled outfits; one little girl is even clutching a saccharinely cute teddy bear.
