This is a Mademoiselle Non Non NO NON sleeveless long dress. It can be worn as a sleeveless dress on its own, or as a jumper skirt. It contains linen, so the fabric has a crisp texture. There is no size indicated, but I believe it would fit M to L sizes. Shoulder width: 38 cm Body width: 48 cm Length: 116 cm Material: 80% Polyester, 20% Linen; Unlined This is a new, unused item, only tried on.
