S izz l er s these top tren are h o t BY LINDA BACHRACK Rimless sunglasses: The new fashion statement in summer eyewear is the cool, sleek rimless look. The Cartier Decor C collection personifies this look with a plat- inum model in a refined, narrow curved rectangle. Large aviator styles also are tres chic. Glasses available at Cartier, Somerset Collection, Troy. Black and white: Black-and-white combina- tions offer a sophisticated approach to summer dressing. It's especially eye-catching when inter- preted in leather on this dress from Saks Fifth Avenue. There's nothing more flattering than black and white for swimsuits. And these Carol Wior Slimsuits from the Bobette Shop in Waterford take an inch or more off specific problem areas. With a matching sarong, these suits will have you strutting the beach in style. Flower pins: If you've taken to wearing an oversize silk flower on your shoulder, you're probably a fan of HBO's Sex and the City. Sarah Jessica Parker (Carrie on Sex) has a way of influencing everything from fashion accessories to the drinks we order. Flower power is ultra-sexy. Have fun with it.
