Want a bit of luxury with your workout? Neither did we, until we found out about *****L (as in cinq étoiles luxe, or "five-star luxury"), a French brand (of course) that makes sportswear out of materials like silk, astrakhan, and mink. (Note to plebes: They also sell stuff in cotton.) They just opened their first Paris boutique (pictured), where you'll find a mix of the conservative (polos, smart-fitting gym shorts) and the decidedly less so (athletic jackets emblazoned with giant lilies). Just consider yourself warned: A visit to the 3rd arrondisement store may dim the luster of the nearby Ritz—and those guys won't even sell you a tracksuit.
