Not wearing undergarments

Main article: Going commando

Not wearing undergarments under one's outer clothing is also known in American slang as freeballing for men or freebuffing for females; the terms going commando and going bareback are also used for both sexes.^[5]

This trend shows that a few consider underwear unnecessary for hygiene, especially for modern people who bathe every day.

In situations where a certain amount of body coverage is required (legally or socially), people who prefer to go clothes free might enjoy not wearing undergarments, as that is the closest they can get to nudity. For others, there may be sexual motives; undergarments are the final physical barrier to sex, and not wearing them might be arousing.

Cycling shorts and swimwear such as board shorts are usually worn without underwear. Often the same applies for a kilt; the uniforms of several Scottish military regiments mandate wearing no underwear with the kilt except at specified occasions.^{[citation needed]}

Women's panties or knickers

There are also many types of long underwear, union suits, and other variations of men's underwear. Some underpants also have a fly. These usually do not allow detachment at the waist; elasticity allows them to be taken on and off. Usually the fly of underpants avoids exposure of the skin just by an overlap of cloth, without buttons, etc. Such a property may be one of the criteria for boxer shorts not to be suitable as outer clothing.

Today, there are many specialized types of underwear made for sexual purposes, such as edible underwear or crotchless panties. Most of these are meant simply to display the body or genitals in certain ways, while some are intended to provide genital stimulation as well. Frederick's of Hollywood is an example of a business centered around manufacturing and selling such underwear.

Religious significance

Mormon Temple garments (two-piece style)

Tzitzis

Undergarments can also have religious significance. For example:

• Some members of the The Church of Jesus Christ of Latter-day Saints wear special undergarments after they have been endowed in a temple to help them remember the teachings of the temple.^[3]
• Many Jews wear a four-cornered garment called a tallit katan, with tzitzit (fringes) attached at the corners^[4].
• Some Hindus wear a sacred thread, called the Yajñopavītam, underneath their clothing.
• One of the five articles of the Sikh faith is underwear called kaccha.
