The designer is Takayuki Kono.
Kono served as an assistant to Yoshio Kubo for approximately eight years at yoshio kubo / undecorated MAN. Starting with the 2016 autumn/winter season, Kono took over the baton from Yoshio Kubo and was appointed as the designer.
In 2018, the brand added womenswear to its collection and changed its name from "UNDECORATED MAN" to "UNDECORATED." Aimed at modern individuals seeking "higher quality everyday wear," the brand offers basic, seasonless items.
