Karasu-zoku, the 'crow tribe', is a Japanese aesthetic of all-black designer streetwear from the 1990s and 2000s, originating in Harajuku around expensive monochrome avant-garde dressing. All-black ensembles are the whole proposition. Loose Japanese streetwear silhouettes shape them. Black knitwear covers the tops. Wide black trousers cover the bottoms, with minimal dark accessories.
