Tag says L. I'm a S/4 and it fits me also fits my daughter M/8 and it could fit a L as tagged. I think this should be one size fits all because I'm a small and it fit me, wrap around and tie to fit your size. I just never wore it. Bought for a cruise and it sat in the suitcase. Light and airy soft cotton, cute with ruffles. Inside button and side tie, wrap around. Adorable with a bikini top by the pool or a black tank and heels for evening. FINAL MARKDOWNs in my closet. Everything has reduced prices. Bundle with my items or other sellers items and only pay shipping on ONE item for the entire bundle. I just shipped 8 items for 5.95 to someone across the country! My photos are my description so check out and ask any questions. Smoke Free. Pet Free home.
