First off, it's weird that the pic on the package shows a different pic. I know cos I've worked in the fashion industry and when I see a bra that's different I can tell immediately. And the pic on the package is diff from the bra inside the package. The cup shape is different. Anywa this isn't a huge deal but wanted to point that out.
Second, I used to own a bra shape like this, not the wing sticky version but the regular version. It was nice, but ended up giving it to my mother who had a better use of it. That one made my breast 2 cus larger and it looked awkward on me but great on my mother.
This one is no push up or anything and I thought it would go great with my wedding dress however because the cup is too soffit made my breasts weird shape. Not to mention it didn't hide under the dress!! It came out at the top so def cant wear it!!!! Decided to keep the other bra that's not U plunge like this. It seemed to hide under the dress better. This U plunge bra would only work on halter dress that I own, I couldve kept it but why bother having a bra that works best only on 1 type of dress!
Overall I'm very disappointed that the companies that make backless bras aren't working harder to make the bras better. it's very odd that they didn't make under the cups sticky too.  I would think that would hold the cups better. Top of the cup part really doesn't need to be sticky. It's under the cup that needs to stay put so tht the cups will hold up the breasts well. Besides, some other reviewers mentioned about the sticky bras that it doesn't allow the breasts to breathe, etc. this would prevent that problem. Sigh. I wonder what those designers learned in design school!
