Almost nothing is more universal than underwear. We all wear it. Or at least we all should wear it. But throw the word Mormon in front of it and all of a sudden it's scary, weird, or "magical." But Mormon underwear is, in fact, just underwear. I could go into detail but then what sort of lady would I be. I'll give you a hint, underwear designed to show deference to God probably isn't sexy.
Okay: to the untrained eye, it's just a white t-shirt and very thin white shorts. In fact, you might mistake them as such and accidentally wear them. True story. Garments fall just above the knee for both men and women, which prompt Mormons to dress more conservatively. You'll be hard pressed to find a Mormon lady sporting a mini skirt.
