Why Do Mormons Wear Weird Underwear?

The type of underwear worn by Mormons is used as a marker of the their faith and to show their devotion to their religion. These articles of clothing are typically referred to as "garments" or "temple garments."

Mormon underwear for both men and women consists of a white T-shirt paired with white boxer briefs that are slightly longer than typical boxer briefs. Young adults receive their first pair of garments after they participate in the endowment ceremony, which takes place inside of the temple and is closed to non-Mormons. Mormons are required to wear the garments underneath their clothing both day and night as a symbolic reminder of the covenants the members make during the endowment ceremony. The garments are viewed as a symbolic source of protection from the evils of the world, although some wearers view the garments as a literal form of protection.

Temple garments are primarily worn by members of The Church of Jesus Christ of Latter-Day Saints, also known as the LDS Church, and by members of some fundamentalist Mormon churches. The LDS Church believes that the garments, when properly worn, provide protection against evil and temptation. The garments also serve as an outward expression of the wearer's inward commitment to follow Jesus Christ.
