I am a 34B and ordered the C cup as they stated to do. The cup did not even touch my breast and the sides were to narrow. If you have back or underarm fat this will not work as you think. Looked as I thought just was not for my body, I'm 5 feet and 155 lbs.While the product is sturdy and I can see it working of you have C's or below. I ordered a 36E and I am a 36DDD, thinking I would be safe. That was not the case, I would have to buy two of these and sew them together to work for me.Felt a little snug but it came with many adjustable straps so it had a good fit in the end, although I had to adjust the band all the way. Its very versatile, you can switch between the transparent or nude straps, you can wear crossback, halter, or normal so they will help in wear many outfits. Can't wait to try it with my dresses.Overall this was disappointing. Did not hold the breasts in place well. Perhaps that was an unreasonable expectation. Would not buy it again.First off, I really wanted to like this bra. I have a wedding I’m going to this weekend and I have a low cut dress that any normal bra can be seen in.I’m a 34-36B normally so that’s exactly what I ordered. However this bra, regardless of a smaller breast size, has absolutely no concavity to it. It’s almost completely flat across the inside and therefore my breasts just keep shifting around in it without any place to “sit”. I added a close up so you can hopefully see my disappointment.The second disappointment was although you can’t see the part that connects the two cups of the bra that normally would be seen in a deep V dress, the cups themselves were still very evident, and the whole point was to not be able to see the bra at all. I could have fixed that part with some double sided tape, but I honestly dislike it so much I’m just going to return it.This was the third plunge bra brand in the fifth size and my conclusion is, this style of bra only works for women with a nice perky boob job. I have a fair amount of natural boobage, but in all the styles I tried there was space in the cup above my boobs even when going down a cup size. Sadly, I’m going to have to give up on this quest.Too big. Gave it away.Love this bra. I uploaded a pic of me in my white dress wearing the white 34 d bra I ordered. Fits like all other 34 d and is comfortable.... most importantly it did not show under my plunging neck line dress shown in pic. As you can see the bra lifted and pushed together my cleavage. The bra was perfect for the dress I'm wearing.Fits perfect and no one can notice the transparent straps at the back!
