Ordered a B cup and it fit perfectly! It is seamless against your skin and isn't noticeable under tight dresses at all. It feels like jelly on your breasts. I can reuse one probably about 7 times or more, and the stickiness lasts a long time, even when you're just storing it waiting to use it again. It comes with a clear, purple zipper pouch so it's very convenient for storing. I've never had it fall off on me before, even after sweating or after a long day. No rashes, no irritation either. It's a great price compared to big stores, where the price of sticky bras can be $18+. Overall very easy to use and does the job exceedingly well.
