Yohji Yamamoto is a Japanese fashion designer based in Tokyo and Paris. Considered a master tailor alongside those such as Madeleine Vionnet, he is known for his avant-garde tailoring featuring Japanese design aesthetics.

Yamamoto debuted in Paris in 1981. In an interview with The New York Times in 1983, Yamamoto said of his designs, "I think that my men's clothes look as good on women as my women's clothing. When I started designing, I wanted to make men's clothes for women." More recently he has expounded: "When I started making clothes for my line Y’s in 1977, all I wanted was for women to wear men’s clothes. I jumped on the idea of designing coats for women. It meant something to me – the idea of a coat guarding and hiding a woman’s body. I wanted to protect the woman’s body from something – maybe from men’s eyes or a cold wind."
