Barneys New York

While these days any clothing boutique worth its counter-side Hanky Panky display boasts a "denim wall," none can touch the selection at the downtown Barneys. The racks and tables and shelves of jeans include the blue-chip (True Religion, Paper Denim & Cloth), the hard-to-find (Acne, Edun), and the affordable (J Brand, Cheap Monday). Bargain hunters salivate over the store's semi-annual sale, which recently saw a pair of $300 Ksubis go for less than $60.
