Kooples only for deep discount, or never. Material and quality is very very average. It's not cheap either. It's priced around eg range. It's something you'd buy if u like the hedi/slip aesthetic but can't afford the clothes.
it actually costs a lot of money to look like a hobo. edit: Found it! c4est and sipang http://www.styleforum.net/t/254278/official-obscure-high-end-japanese-trends-youre-not-cool-enough-for-megathread/320_80
