I think its very interesting to think about what the designers themselves wear. Most wear their own clothing, but in a very minimal way. I know simon spurr has mentioned he wears the same cashmere sweater and jeans everyday (his collection is equally reserved). Ervell wears an oxford shirt, levis 501's, and docs in the photos I've seen. Drew Keith wears a leather, tee, faded PS, and GATs (5). On the other, Geller seems more adventurous. I have no idea what the designers of the big fashion houses wear. The designers try keep their anonymity it seems.
