I didn't know there even was a soho one, hah. But yeah, it's been gone for a long time. Think it might be a Marni store now. IF doesn't carry Yohji, just fyi. If it's Yohji you want and you're staying downtown, check out Hotoveli on W. 4th in the West Village. They had some cool pieces when I last stopped in. If you want to travel a little, Barneys of course has Yohji, and Atelier is still open for the time being. I stopped in there on Friday and they had some Yohji left, and it's all 50% off right now.
there are no yohji stores in ny or the us to my knowledge. the soho store is now alexander wang and has been for like 4 years. the meatpacking store has been closed even longer i believe. there is a y3 in soho, which i think is very underrated on this forum.
there is a marni store in soho as well (right across from verssace)
