language culture Maturity 11-13 Next article →

A thong is a specialized garment used globally as underwear or as a swimsuit.

While the front often resembles standard bikini bottoms, the rear is designed with minimal fabric coverage. This design typically covers the genitals, anus, and perineum while leaving most of the buttocks exposed. The back usually consists of a thin waistband connected to the front by a narrow strip of material. This strip is specifically designed to be worn between the buttocks. Because of this unique shape, the term "thong" is often used as a descriptor for other garments, such as leotards or one-piece swimsuits, to indicate they are "thong-backed."

There are several distinct styles of these garments categorized by their rear construction. The G-string is a common variation where the back consists only of a thin, often elasticized, string.

Some sources distinguish the thong as having a one-inch strip of fabric, while the G-string is even narrower. Other intermediate styles include the V-string, the T-back, and the Cheeky style. A C-string is another unique type that does not use a waistband.

Additionally, the tanga is a style of briefs featuring small panels connected by strings at the sides. These garments are manufactured in many materials, including silk, cotton, lace, nylon, and spandex.

The history of the thong is closely linked to the evolution of human clothing. It is believed to be a descendant of the loincloth, which is likely one of the earliest forms of human attire. Loincloths likely originated in the warm climates of sub-Saharan Africa nearly 75,000 years ago.

Many tribal groups, such as the Khoisan of southern Africa, wore such garments for centuries. In the modern United States, the thong had its first public appearance at the 1939 New York World's Fair. Later, in 1974, designer Rudi Gernreich introduced the modern thong bikini in response to a ban on nude sunbathing in Los Angeles.

Cultural naming conventions for the thong reveal much about how different societies perceive the garment. In Brazil, the word tanga is used, and a common metaphor is "fio dental," which means dental floss.

In China, the garment is called dingziku, which translates to "T-character pants," referring to its shape.

In Israel, the term khutini' is used, derived from the word for string. Bulgarian speakers use the word prashka, meaning "slingshot," while Spanish speakers may use the term colaless to reference the bareness of the buttocks. These diverse names highlight the garment's presence across many different linguistic and cultural landscapes.

Fashion trends regarding the thong have fluctuated significantly over the decades. In the 1980s, pop stars like Madonna and Cher wore them on stage, helping the style enter the Western mainstream.

During the 2000s, a trend emerged where people wore low-cut hipsters to intentionally expose the thong above the waistline. This look was popularly known as a "whale tail."

While this specific trend declined in the late 2000s, thongs remained a significant part of the market. In the early 2000s, thongs accounted for 31% of the women's underwear market. By 2022, sales saw a surge driven by a revival of these older trends among Gen Z consumers.

Men's and women's thongs feature specific design differences to accommodate biological needs. Men's versions often include a vertical seam to create a pouch for the genitalia, frequently using stretchy materials like cotton-Lycra for an ergonomic fit.

In contrast, the equivalent section in women's thongs is typically flat and seamless, though the fabric is often thickened with a cotton gusset to cover the vulva. While men's thongs were once primarily associated with the dance belt used by bodybuilders or male strippers, they are now widely available through major retailers like Calvin Klein and Kmart.

People choose to wear thongs for a variety of practical and aesthetic reasons. One major functional reason is the prevention of visible panty lines under tight clothing. They are also used to minimize tan lines when worn as swimwear.

Additionally, some wear them to prevent the fabric from "riding up," which reduces the need to adjust clothing in public. Other motivations include comfort, fashion consciousness, or the desire to feel more adult. The rise of buttock-enhancing fitness trends in gyms has also coincided with the continued popularity of thong-style swimwear.
