I was very skeptical about this item. I wear a 32D, and that's not too big but I still doubted that this could give any sort of support but I needed something strapless which is difficult for me because it requires dropping to a 30DD to find a bra that won't slide down during wear. Well I have to say I am pleasantly surprised by this. It does work better with loser fitting or low neckline clothes because it has a tendency to just jut out of your chest in tighter clothes, and it doesn't necessarily make you look like you are wearing a bra, just like you are lucky enough not to need to. However it take A lot of practice, i fear the number of times I had to re position it to get it to look even the adhesive may wear off much sooner than is intended, so I will need to keep watch for that.
