The Isla is a romantic, slightly oversized shirtdress shape, and this one is made of one of our go-to fabrics: a relaxed, striped cotolino from Italy. It's got a point collar, puffed bracelet-length sleeves with elasticated openings, and a full, tiered skirt, plus an optional self-tie sash to cinch the waist or leave off for a more voluminous silhouette.
