"Y's BANG ON!" is a seasonless brand, whereby each garment is associated with a number rather than a collection. The name is a pun on the idiom "bang on" and the Japanese word for "number," 番号 (bangō). Each garment features a tag printed with the Y's logo (as hand-drawn by Yamamoto himself), and stamped with the number of the garment. The line includes completely original designs, as well as pieces inspired by the Yohji Yamamoto archives.
