If there are ever time when you can't wear a normal bra, but you still want to make your body look good, then an adhesive bra might be just what you're looking for. Maybe you are wearing a dress that has an open back, or you want to have some extra support while you are in a swimsuit. An adhesive bra works by holding your breasts in place with a sticky substance. It might be a strange sensation, but you'll soon get used to it. Adhesive bras are completely hidden beneath your clothes, so no one will ever know you are wearing one.
