The bodice, from the waist up, has elastic. Labeled as M, but it's closer to a free size. Flat measurement: Bust 34cm, stretches to 45cm Length from back: 110cm I think this item would be great for resorts and other vacation spots. It can also be worn off-the-shoulder. ------------------------------------ I bought this here, but it doesn't suit me, so I'm selling it. Only tried on indoors. The elastic in the back had stretched, so I had it repaired. Please understand that this is a pre-owned item that has been stored at home. Season: Spring/Summer Stains, tears, odors, etc.: None Pattern: Stripes
