There's not much to this teddy, but that's part of its charm. The vibrant red color (which doesn't fade in washing), the sexy lace, and the additional playful cuffs make this teddy a winner every time. The sizing is true to size with a lot of flexibility to wear a smaller than normal size. Cup size is for the medium, is approximately up to about a 36C/D. Currently a 36DD, and I spill out of it a bit. It's lightweight and can be worn under clothing. It is not complicated to put on at all. This fiery teddy can spark any evening.
