Briefs (or abrief) are a type of short, form-fittingunderwear andswimwear, as opposed to styles where material extends down the thighs. Briefs have various different styles, usually with awaistband attached to fabric that runs along the pelvis to the crotch and buttocks, and are worn by both men and women.Swim briefs are a variation used as swimwear.[1][2]
Men's classic briefs were first sold on January 19, 1935, by Coopers, Inc. (now known asJockey International), inChicago,Illinois, atMarshall Field's department store. They dubbed the new undergarment the "Jockey", because it offered a similar degree of support as thejockstrap (one style of which is also called "jock briefs" or "support briefs").[3] The designer of the new style was reportedly inspired by a postcard he had received from a friend visiting the French Riviera depicting a man in a very short, form-fitting bathing suit. 30,000 pairs were sold within three months of their introduction.[4] In theUK, briefs were first sold in 1938.[5] Soon, shops were selling 3,000 pairs of briefs per week.
In the 1960s, fashion underwear was introduced in the United States, and, after a period of decline, became more prominent in the 1970s as the belief that wearing fashionable underwear was less masculine declined. By the 1980s, men's fashion briefs became more popular in the United States;[3] in 1985 they made up 25% of the men's underwear market, while they had almost no sharec. 1980. TheUnderoos andFunpals fashion brief brands for children were introduced around that time. According toHanes marketing director John Wigodsky, women purchased fashion briefs for their husbands for aesthetic reasons, and therefore fashion briefs became more popular with men.[1] In 1990 Tom Zucco of theTampa Bay Times interviewed menswear sellers: one worker stated that about 50% of theunderpants sold were white briefs.[6]
During the 1990s to early 2000s, the popularity of men's briefs declined in the U.S. andboxer shorts became widely portrayed as the casual and masculine choice. However, more recently, as men's fashion has trended in favor of more tailored clothing, form-fitting underwear such as briefs have come back into style, including newer styles likeboxer briefs.[7][better source needed]
In the United States, "jockey shorts" or "jockeys" became an often usedgeneric term for men's briefs. More recently, "tighty-whiteys" (and some less popular variants of it) has become a commonly used slang term for male briefs, especially traditional full-cut ones.[8][9][10]
In theUK the term "jockeys" did not catch on and men's/boys' briefs are often referred to as "Y-fronts". The term derives from thegenericized trademark "Y-Front", property of Jockey International.[11] It, in turn, derives from the inverted Y-shape formed by the seams at the front of theunderpants.[12] Thecolloquialism is used even when the fly opening may differ in style, and not actually form the shape of the inverted letter "Y" fly on Jockey brand briefs.
In Australia, male briefs are referred to as "jocks" but should not be confused withjockstraps (more specifically used by athletes) which expose the buttocks. Australians generally use the word “briefs” to refer to thebikini-style briefs for men.
"Briefs" additionally is the official name of a specific cut offemale underpants similar to male full-rise briefs.


Traditional size briefs for both sexes cover the uppermost part of the thigh and extend upward up to (or cover, depending on the design) the navel at thewaistband. This style is often referred to as "full rise" or "full cut". There are also "low rise" and "mid rise" styles whose measurements vary between manufacturers.
Bikini briefs or simplybikini in context are a style of brief with narrow material at the sides and which often have a low rise; reminiscent of abikini, and are designed for either men or women.
Men's briefs often have afly—a covered opening on the front of the garment which allows for convenience in urinating. There are several different fly designs in common use, including the standard vertical fly, the horizontal fly, the Y-front fly, and others. The use of a fly is optional, and many styles do not include them; notably bikini briefs. Briefs without a fly-opening are often referred to as "slips" or "slip-briefs", a term that also sees use in non-English speakingEuropean countries.[citation needed]
Unlike boxer shorts, briefs hold the wearer'sgenitals in a relatively fixed position, which make briefs a popular underwear choice for men who are participating in athletic activities or who prefer more support than loose-fitting underwear can provide.[citation needed] In addition, boxer shorts and boxer briefs may ride up the body uncomfortably when the wearer is running or wearing form-fitting attire. There are different names for variations of the brief depending on the height of the brief at the sides, with names includinglow-rise, mid-rise, full-rise, sport, active, hip, and bikini. Some briefs have the cut all the way to the waistband on the side, called atanga.

"Briefs" also refers to a style of women's and girls'panties that is typically cut with a high waist to provide full coverage of thehips andbuttocks. A control brief is a kind of high-waisted pantygirdle. French-cut or high-cut briefs expose more of the front part of the thigh, whileboy briefs have short legs, similar to men'strunk briefs, often combined with a lower waist. Full briefs cover the woman's upper-thighs, with some styles covering up to the navel. Midi briefs are a hybrid between boyshorts and a full brief, sitting on the woman's hips while providing full-coverage. Brazilian-style women's briefs, usually made ofmodal-fabric, have high-cut legs and sit low across the hips. The back is wider than athong, but often smaller than other women's brief styles, making Brazilian briefs an ideal choice for women to avoid showing avisible panty line without having to wear a thong.
Briefs is also the name given to costumed outerwear worn by female dancers and athletes in sports such ascheerleading,figure skating, andtennis. These briefs are typically worn under a shortskirt; they may be attached to the skirt or dress body, or a separate garment (cheer briefs, or spankies).[13]
Research on the effect of men wearing tight underpants, like briefs, onmale fertility is inconclusive. Briefs, boxer briefs, etc. have been blamed for negatively affecting sperm production, since they may interfere with cooling of thetestes.[14] However, not all research has come to the same conclusion. A study in the October 1998Journal of Urology, for example, concluded that underpant type is unlikely to have a significant effect on male fertility.[15]
