If I could leave 0 stars, I would. Im a C/D cup and I although I purchased the correct size, they would not stay stuck on, although I followed every instruction. The silicone is rather thick so visible under thin clothing (making them not suitable with my particular dress, if I could get them to stay in place). Would not recommend. Company has clearly paid for 5* reviews, as a lot have been left by men. Don't be fooled, this product is useless!
