British cult favorite Topshop, which has only a handful of U.S. stores, is a master at pumping out of-the-minute-fashion at reasonable prices. It can be a madhouse, and items sell quickly, but it's worth fighting the crowds. Slinky dresses are around $130, and jeans and jumpsuits are about $90. Coats and shoes are also standouts. Male stylistas can browse through the ground-level Topman.
