The people who are saying that this doesn't work for D cups are wrong because I am a 38 D and wow does this work! It took about ten minutes to figure out how to wear it but when I was finished I put on a shirt and tried to see how my boobs looked, they were perky and looked even bigger than usual! The adhesive is very good also, washing it super simple too. I am really happy I bought this. I would definitely buy this again.
