I bought these for a formal even I am attending. I have a gown and need a little extra help. I bought special medical glue to wear with them since I cannot wear a bra with the gown. They are washable so that is good. I tried them on in bathingsuits and they fit in the cuts, not sure I would wear them running around or swimming, seems like it would be something extra to worry about, but they do fit and look ok in the suit. I wore them with a halter dress for a photoshoot and they looked natural in the dress and in the photos. They work. They are not uncomfortable and look natural. They even have a nipple on them-not sure why lol but they do.
