Comme des Garcons is headed by Rei Kawakubo and has been around since 1973.
This is their most recent collection, looks like toiles mish mashed together
This collection experimented with biker jackets and control and looseness and tightness.
and this is a particularly interesting collection for me, fall 2009:
Iconic collections most people recognise Kawakubo for are the lumps and bumps collections and the decayed/ distressed collections, but for me this is the garment that made me really fall for Kawakubo, it's in a massive book I got for my birthday years ago and it's one of my favourite pieces in the whole book.
