The clubby ambiance is a natural fit for Rock and Republic jeans ($150-$250) and playful Paul Frank T-shirts ($24). Other of-the-moment offerings include jeans by Frankie B. and Hudson, colorful Akira-brand clothing, and funky tops by Religion ($79-$120). The Clark Street store has slightly more conservative styles. Also find a denim bar with up-and-coming lines such as 575, People's Liberation, and Blue 2.
