2. Fendi's Runway Blouse, $1,390 at eluxury.com: There's a casual quality to this elegant number, as if you slipped it on without a moment's notice. And yet the deep back is sensual and deliberate. Wear with a white camisole for day to maximize the piece, and wear without one at night for optimal viewing.
