This is basically a thermal dress. It\'s material is super soft but super not breathable. It\'s basically a thermal that is a cute alternative for the fall or winter to leggings and a top. That being said, it might be a nice basic to add to your winter wardrobe. I am 5\'6 140lbs and the Large fit snug on me. It shows every dimple and curve of my body. I think even if I lost 10lbs this would be form fitting. Definitely size up, as I usually wear a small or medium in dresses.
