Undergarments can also have religious significance:
- Judaism. Male Orthodox Jews wear a four-cornered prayer shawl called a tallit katan, which has tzitzit (fringes) attached to the corners, draped over their shoulders. To conform with societal dress codes, a tallit katan is often worn beneath one's shirt, but above an undershirt as it should not come into contact with the skin.
- Mormonism. Most members of the The Church of Jesus Christ of Latter-day Saints (Mormons) wear special temple garments after they have been endowed in a temple to help them remember the teachings of the temple.
- Sikhism. One of the panj kakaar (five articles of faith) that Sikh men wear is a type of underpants called the kaccha, which are similar to boxer shorts.
These usually have an elastic waistband, a crotch to cover the genital area which is usually lined with absorbent material such as cotton, and a pair of leg openings which are often also elasticized. They either have very short or no leg sections
Has a narrow strip of material along the centre of the garment's rear which sits between the wearer's buttocks and connects the front or pouch to the waistband behind the wearer. Thongs are sometimes worn to reduce "panty lines" when wearing tightly-fitting trousers.
