right here. While originally intended as toupee tape, it far surpasses regular old double-sided tape when you're in need of a fashion fix. 1) Completely sweat proof 2) won't damage clothing or skin 3) It'll keep anything perfectly in place.
Great for bra and other straps, heavy beaded necklines that tend to pull too low, keeping plunging necklines in place and about a hundred other things! Trust me, you won't find anything else backstage.
