Gave my boobs weird shape... however it stayed on outside in the Texas heat in direct sunlight at 5:30 pm for the wedding I was in. I am a size D chest, got the D-Double thickness and that might be what gave me the weird protruding shape. If you're a D go for normal in my opinion. It won't give you this amazing shape if you go thicker.

Helped with the sheerness of the dress I had, and was easy to clean and remove.
