Darling of the fashion set, thanks to his perfectly proportioned "king of cling" dresses, Alaïa is considered a master at his game. You don't have to be under 20 to look good in his garments; Tina Turner wears them well, as does every other beautiful woman with the courage and the curves. His boutique/workshop/apartment is covered with artwork by Julian Schnabel and is not the kind of place you casually wander into out of curiosity: the sales staff immediately makes you feel awkward in that distinctive Parisian way. Think $3,500 is too much for a dress? The Alaïa stock store (same building, different entrance) takes 50% off last season’s styles, samples, and gently worn catwalk items. Access it at 18 rue de la Verrerie.
