Speaking as a male
, i know this for a fact.
My school throws a couple of drag balls a year. Being of the adventurous sort (occasionally) i decided to go in a simple female getup-- skirt and t-shirt with fake breasts. But, not having a training bra handy, I had to make my own.
The only things i had at first were balloons, unfortunately these had a way of migrating across my chest making me look like a woman with a mindbogglingly bad plastic surgeon. Or popping, and that's no good at all. Besides, they were very large and torpedo like.
So i went with Socks. While i could keep them in a reasonably tight tshirt for a little while, it was uncomfortable and to dance with them would be out of the question.
So i employed the only reasonable technique duct tape.
Duct tape chafes. This includes the sides and corners if not done properly.
Duct tape shows if put on improperly. I readjusted that t several times.
Duct tape Hurts when it is pulled off. Especially in sensitive areas.
Duct tape leaves a mark when removed.
