Panties are women's form-fitting underpants. Typical components include an elastic waistband, a crotch panel to cover the genitalia (usually lined with absorbent material such as cotton), and a pair of leg openings that, like the waistband, are often made of elastomer. Various materials are used, but are usually chosen to be breathable.

Panties are made of a variety of materials, including cotton, lace, latex, leather, lycra, mesh, nylon, PVC, polyester, rawhide, satin, and silk. Construction typically consists of two pieces (front and rear) that are joined by seams at the crotch and sides; an additional gusset is often in the crotch, with the waistband and leg-openings made from elastomer.

The earliest known use of underwear that resembles modern panties dates back to 4,400 B.C. during the Badari period in Egypt.^[1][2]

In the United Kingdom and occasionally in other Commonwealth countries such as Australia,^[3][4] Canada and New Zealand, panties may be referred to as "knickers", "undies", or simply "underwear". The last two of these are gender-neutral terms and can be used for either male or female styles of underwear bottoms, the American English equivalent being underpants. In Australia, male underpants are often referred to as "undies",^[5] although the word can also refer to panties.

Panties are classified into various styles based on criteria such as the amount of rear coverage, width at the sides and height at which they are worn. These categories are not necessarily distinct and usage may vary somewhat among brands:^[6]

• Adhesive panties are sometimes described as strapless/stick-on panties. They are a form of micro-panties that cover the bare minimum parts on the front and back. They are useful when women do not want the panty line to be visible.
• Bikinis, like hipsters, sit at hip level, but the fabric of the side sections is narrower. With the string bikini type, the side sections disappear altogether and the waistband consists of only string-like material. There may be less rear coverage with the bikini style.
• Boyshorts cover the hips and are named for their similarity to boxer briefs, a variation on boxer shorts. Some resemble men's briefs, complete with fly and contrast trim. Unlike men's briefs, this style is usually lower cut. Boyshorts often cover most of the buttocks.^[7][8]
• Briefs rise to the waist, or just below the navel, and have full coverage in the rear.
  • Classic briefs have the waistband sitting very high on the waist. The leg holes are small so the underwear cover as much area between waist and thigh as possible. Sometimes called "granny panties" because they were the standard underpants in previous decades and have a connotation of being worn by older women.
  • Control briefs are designed to offer support while giving a slimmer appearance. This type usually contains a stretch material such as spandex and may extend above the waist. Some have an extra firm panel to flatten the tummy. Some also compress the buttocks, while other control briefs are designed to avoid compression of the buttocks. Others merely lift the buttocks and have holes cut out for maximum fullness of the buttocks.
  • High-cut briefs sit higher on the waist, providing more coverage in the midriff region. They are designed with larger leg holes and narrower sides to show off more leg and allow more freedom of movement.
• Cheekies can be styled as a hipster, bikini, or boyshort in the front, but in the rear, they are designed to hug the buttocks, and have a seam or ruching to make the fabric sit partially between the cheeks to accentuate the shape. They leave the outer 1/3 to 1/2 of each cheek exposed and often have a lace or scalloped trim.
• Hipsters are a blend between bikinis and boyshorts. They sit on the hips of the wearer and are worn slightly below the navel.
• Thongs provide a moderate to minimal coverage with back coverage that is less than a bikini, and the waistband is reduced to a narrow strip at the sides.^[9]
  • The G-string has a vertical string at the back, which connects the crotch to the waistband, sometimes featuring a triangle of fabric which is sometimes referred to as a whale tail when it peeks out above the waistband of low riding pants.
  • The T-front is a type of G-string in which the string also reaches the front part. It provides almost no coverage while still maintaining the basic hygienic underwear functions and covering only the genitalia. Usually it is built by strings only, sometimes with more fabric or lace around the waist.
  • Thongs have a waistband similar to tangas, but the rear coverage is mostly cut away. The crotch is triangle-shaped, as it narrows to a thin strip toward the back and sits between the buttocks, becoming wider towards the top where it connects to the waistband. Like the G-string, if the back fabric peeks out above the waistband of low riding pants, the result is also called a whale tail.
