CmojskSticky Bra, Backless Strapless Bra Push Up, Adhesive Invisible Lift Up Bras 2 Pairs Black/Beige

Does it work well?

How do they work with sweat?

On a very hot sweaty day, the bra came off, is there any adhesive product to revitilize the bra to?

Could these be worn all day? true to size for b cup and do they add lift? I've tried a few of the bunny ear ones and they were too big or too small.
