It's streetwear meets anime. The concept of streetwear:
A fashion movement that combines elements of countercultures around the world with modern street style. Popular influences streetwear draws upon include, but are not limited to:
-
Youth subcultures like Skate or Goth
Artistic movements such as punk, grunge, and hip hop
Anachronistic artistic motifs such as cyberpunk or Renaissance art
High fashion and avant gardism
Active-wear such as athletic or military clothing
So basically that, with anime.
