A relaxed, men's-like fit with a casual feel. This casual piece for adults was created by Takayama, who is good at coordinating jackets. The back of the neckline is slightly raised, so the neck is not too loose and the finish is neat. The sleeves are moderately loose, so they can be worn with any item underneath. It can be used with a wide range of outfits, such as denim styles and one-piece.
