After working through some power issues, Lanvin's first New York boutique bowed last week on Madison Avenue. The 3,550-square-foot space is fashion porn for the well-to-do set, filled with daintily distressed dresses and colorful silk cocktail frocks, bejeweled heels, cascading skirts, and python bags dangling from gold chains. The store spans three floors (the top two in the five-story building will be turned into the brand's offices) and is meant to resemble a luxe women's club, decked with zebra-print rugs, Art Deco chandeliers, Louis XV–style couches, and black-and-white photos from the Lanvin archive. The cream-colored third floor is devoted to the Blanche bridalwear collection; the second floor offers shoes, jewelry, and the fall collection; and the first floor is devoted to spring apparel, handbags, and gifts. Click ahead to admire the high-end wares.

Lanvin, 815 Madison Ave., nr. 68th St. (646-439-0381); M—S (10—6).
