None or the sticky kind are backless and strapless. They look like half a bra and have sticky stuff that adheres to your skin. Or there are the kind that are just adhesive cups that you stick on your breasts and hold them up a little bit. Check with the lingerie department at department stores or sometimes sex shops that sell clothing have lots of unique solutions for stuff like this. Prolly a no-go if you're much bigger than a B. I know they don't usually work for me. Cute dress but I'd never be able to wear it for the bra issue. less
