The dress is so cute, it is perfect for a cocktail attire event or just to have. The material, I was not expecting. It is super stretchy, however still very snug. I can even go braless due to the material. I normally wear a L in dresses unless its short or tighter material and decided to go with XL to be safe. GLAD I DID! lol I have an hourglass figure. I am 5'5", 217lbs, DDD, with 52" hips. It literally fits perfect, a large would not have been able to fit at all. If curvy, I suggest size up. Oh no zipper, also. Its slip on from the bottom or over your head.
