I've tried numerous adhesive bras, and I like this one. I'm a 36 A/B depending on brand. While there's plenty of stickiness, there's no real "holding power" for the girls - no underwire for support - so I'm guessing that this wouldn't work for CD cups. I use it pretty much for modesty. Rather than using the string to make cleavage, I loosened it to make more coverage at the side of the breast. My only complaint is that the cellophane that comes with the bra to cover the sticky parts after washing rips when you remove it the first time, so I substituted Ziplocs. I'm going to buy another set in black.
