Strapless with sticky backing around the top so it won't slip The last 2 photos are the inside of the top with the ribbing and the back bottom where the slit is. Length: Bust : Hidth around hips: I'm 5’3 and 130lbs 36C This dress was altered for my size. One of the pictures shows the amount of fabric left if you need it lengthened. I have never worn it, unfortunately. 🥲 This would be a great dress if you have a special occasion coming up. Living in the south it is hot all the time so many chances to wear it.
