I have this same dress in a brown from last summer / fall! Now if you remember last year this dress ran generously, the medium fit loose like a large. They’ve since fixed sizing, so it runs TTS. I am in the large for boobies and it’s a perfect fit! True to size with a stretchy top! This is a denim, by the way, as it’s hard to tell here. Gorgeous, too, it’s a dark chambray and the bottom half is more structured so it has really beautiful movement to it. Twirlability: 8/10.
