I have two sets of these in different colors. I absolutely LOVE the Feather Lite ones, but hated the original silicone ones. These are very light and you hardly even notice them. They stick on and stay on, yet you can peel them off and they leave no residue. I am usually a B cup but the B's I tried on at the store didn't have enough coverage so I went up a size.I wore these today with a sundress. I had no bra straps falling off my shoulders, no strap across the back peeking out of the back of my dress, and no back fat from the band digging into my skin. I didn't keep tugging up my strapless bra every 20 minutes as it slipped lower and lower. It was humid and the Feather Lites still stuck on with no trouble at all. The sales girl at the store told me to wash them once a week with ONE DROP of Dawn dish detergent. She's a D cup and wears these daily, so she says. I'm not sure how she'd have enough support to do that daily but I don't have that problem.I tried the original Nubra a few years ago and they were heavy and fell off whenever it got humid outside. I don't have that problem with the Feather Lites. It does take a while to get the positioning right but it's not a big deal to stick 'em on, then peel 'em off and start over. Once they're on you're good for the whole day. I love these things!I have a strapless backless dress that I need to wear. I have done several test runs and when you combine the Nubra with the Bare Lifts it is very effective. The Nubra does not provide a lot of lift but does bring things together. So when you use the Bare Lifts for the lift, you get as good as an effect as any regular bra I have. The combo is very secure and lasted all day.Note that is does take a couple tries to get the bra positioned correctly.I was surprised at how well this stayed in place and looked pretty much like I was wearing a bra. I ordered my regular cup size and I should have gone up a cup. It was hot and humid the day I wore this and after 6 hours it came off.I received this product damaged from seller BengC. I contacted the seller that the product had been tappered with and they refused to refund my money or send me a replacement item. On top of that since I was stuck with the product I cleaned it up since it was obvious it had been worn before and decided to try it out to see how it worked. Then I could just buy the product from another seller. The product didn't hold me up at all! This is the worst product I've bought on amazon and this is the worst seller I've purchased from! Save your money and don't buy this product!!!!!!As long as you follow the instructions they work great. I really like them and have used them for years. They don't work well if you sweat so I use a roll on adhesive to help but then they do not last as long.Works great in the winter. Sweat will prevent adhesion. Runs Really small, thus order 2 sizes up.This bra actually worked surprisingly well. I'm a 38C and this bra supported my "girls" very well. The adhesive that's used is surprisingly strong, so I had no issues with the bra becoming unglued.i really appreciate the confidence in using this when the wardrobe calls for it. its a bit painful to remove , lol!! but nothing beats confidence!!
