Arqué Shoulder Bag

It is made in white calfskin, smooth and clean, the kind of leather that makes the shape read crisply from across a room. White is a confident choice on a bag this sculptural, because it lets the line do all the work. It measures about 8.9 inches wide, 6 inches tall and 2.4 inches deep, with a 20.5-inch strap drop that places it neatly under the arm or a little lower on the shoulder. The piece is in excellent condition.

The Arqué is a warm-weather bag at heart. It suits brunch, long summer days and everyday wear when you want your outfit to look considered. Inside, plan on the essentials: a phone, a card case, keys and sunglasses in a slim case if you pack carefully. Carry it with a white shirt and linen trousers for a tonal look, or against black, navy and tan for contrast. Keep it away from dark denim on hot days, which white leather never forgives. A summer with it through Saclyn is a pleasant way to decide whether white is really your colour.
