I like Acrimony, but mainly because they carry Geller and Marcus is always very helpful and he's always down to chat.
Just visited MAC for the first time to check out their EG stock and what stood out was they had this ridiculously nice Dries peacoat. Did not know they carried margiela, or used to. Didn't see any, but I didn't look for it.
BUUUT. The best shop in SF. Hands down. Is.
MAAAAS and Stacks.
Steve and Otto really know what they're doing...
