nordstrom rack.
i've seen everything from gucci to louis vuitton to john varvatos.. for men.
as for women.. i've seen BCBG, occasional gucci, etc.
you just gotta dig.. lol their racks of shoes are amazing.. you'll definitely find some diamonds in the rough.
i've found some pretty exclusive vans and converses (not really designer.. but the $90-100 pairs compared to the regular $30-50 pairs.. and i've gotten both price ranges for $20.. all vans and converses were $20 so i picked up at least 3 for the price of one regular price)
