Les Folies d'Elodie is the address in Paris for elegant, feminine lingerie. In this large, lush boutique you can find anything from a 1950s-style cotton bra and panties in pale pink vichy à la Bardot to a risqué sheer-silk nightgown with Calais lace insets. Famous lovers seem to feel at home here, too -- Warren Beatty stops by when he's in town and Bill popped in to pick out a champagne-color confection for Senator Clinton. Métro: Trocadéro.
