I am very disappointed. I have a C-cup and the pad is much too weak to hold the chest while sleeping on the side. The only effect is that I am deeply notched grooves in the skin have, where the pad "glued" was. The really deep notches are bright red and it takes hours until the skin to normal and disappear these things again !! Perhaps the pad works better if you still use a special sleeping bra, I can not judge. The pad itself is in any case totally out waste of money. I wish I could give no star, but unfortunately is not.
