Don’t let the stark, warehouse-like decor fool you—this downtown fashion haven is home to some of the world’s most sophisticated streetwear brands, particularly if your goal is to dress like the current crop of Hollywood it kids. Designer denim is in high supply, although with such labels as Seven for all Mankind, J Brand, Diesel, Rock & Republic and True Religion (all $220-plus), style doesn’t come cheap. Other must-have pieces include a pretty terry cloth A-line sundress by Juicy Couture ($125), outerwear by Cana­dian coat royalty Mackage (from $450), and purses by Matt & Nat.
