Michelle Roth   New York Magazine   The Collection: Superfeminine gowns for a fashion-forward bride. No cookie-cutter designs here. Avant-garde, slinky dresses employ a playful interaction between fabrics (lots of silk and lace) and texture (beadwork, embroidery, etc.).   The Gown: Liquid scoop-neck sheath with shimmering lace and trumpet skirt.   The Price: $3,800.   Where to Buy: Gowns range from $3,000 to $15,000 and can be purchased at Liz Clinton, in Andover, New Jersey.
