Like most of the Mormon cult’s practices, magic underwear seems to be another poorly kept, weirdo secret.
It is basically a set of long underwear but the Mormons believe it protects them from evil.
Their magic underwear are worn under their real underwear. Picture a woman wearing a man’s T-shirt and boxer briefs under her bra and panties, and that’s the look.
Some even sew embroidered patches into their magic undies, adding even more mystical, magical gibberish to the mix.
People might try and argue that it isn’t called magic underwear but if it really protects you from evil then its gotta be magic!
[Ed.} You want an example? I dunno, ask a Mormon for one the next time one comes to your door to convert you.
