I've only tried it on once. I'm selling it because I don't plan to wear it. The size is free size. Quoting from the official website: Full of charm! A cunning mini-dress ♡ The bodice is made of a comfortable, soft knit material, and the skirt is made of a chewy, thick knit material, a Darich-like piece with plenty of playfulness. The plump, rounded gold buttons on the front add an "elegant and glamorous accent" without looking simple. The bodice is fitted, with a change from below the pelvis, and a fluffy flare silhouette, creating a contrast that naturally enhances your style just by wearing it ♡ The color variations are easy to wear daily, and this season's item is perfect for any occasion, so you'll want to get one! Color: Ivory
