Tried it for a low-cut dress and the cleavage boost held up through a whole evening of dancing. The tape didn't peel at the edges even after a few hours, which surprised me. Just make sure to follow the application steps closely or it won't sit right.

Finally found a tape that actually stays put through a full night of dancing without rolling at the edges. The adhesive grips well right out of the package, and it gives just the right amount of lift for my strapless dress. Taking it off was gentler than I expected, though I did follow the oil trick

I used this for a backless dress and it stayed put through dinner and dancing, no slipping or rolling at the edges. The lift and cleavage shaping held up even when I was sweating a little.
