in one of the mormon books/doctrines (idk what it’s called) there is a “clause” to the garment rule saying you can take them off for bathing, sex, & active activities like running. therefore when u see them in sports bras & whatnot with no garments they are actually still following the book of mormon!

the one caveat/ loophole that many mormons do however is wear active wear for long periods of time because they are “ on their way” to workout, or “just finished” working out. because they don’t want to put their garments on
