A long sleeve changes the arithmetic of a dress: it lets you wear a shorter hem, a deeper back or a closer cut and still feel covered. This edit gathers every dress in our range with a full-length sleeve — fitted mesh and lace that sit close to the arm, structured satin with a defined shoulder, soft knits for colder months, and sheer sleeves that cover without warming. It's the answer to autumn and winter occasions, and to venues where you'd rather not carry a jacket all evening. Sleeve fit varies more than body fit between styles, so if your measurements sit between sizes on the arm rather than the bust, size on the arm.
