Never-worn, NWT! Size small, true-to-size. Tried on, but too long for my torso to look/feel good. Top is like a tank top (57% cotton, 38% TENCEL Modal, 5% elastane), bottom is 100% cotton. Saying this as a professional ballerina: this is very ballet coded. I have worn costumes this color (which is why I wanted it to work!). Super light, would be a great picnic or boardwalk dress. Great for a night out.
