A clutch bag is a small handbag designed to be held in the hand, tucked under the arm, and carried without a long strap, which is where the name comes from: you clutch it. It holds only the essentials, usually a phone, a card holder, keys and a lipstick, and it is the classic bag for weddings, dinners and evening events. See the Zimmermann bags at Coveti and our full edit of designer clutch bags for the shapes described below.

Navigator and aviator sunglasses are close cousins in thin metal, and the difference sits in the top line of the lens. An aviator has a teardrop lens that dips low toward the cheek, while a navigator flattens that top edge into a straighter brow bar with a squarer lens, so it reads sharper and more graphic on the face. For a navigator with a softer, feminine finish, start with Zimmermann and then browse the wider edit of designer sunglasses for women.
