Sports Illustrated Swimsuit 2009

A bikini or two-piece is a type of women's swimsuit, characterized by two separate parts — one covering the breasts, the other the groin (and optionally the buttocks), leaving an uncovered area between the two garments. It is often worn in hot weather and while swimming, working, traveling, exercising, dancing, relaxing, and playing barefoot.

The shapes of both parts of a bikini closely resemble women's underwear, and the lower part of a bikini can therefore range from the more revealing thong or g-string, to briefs, and modest square-cut shorts.

Throughout its history, the bikini has spawned many stylistic variations. Topless variations may still be considered bikinis, although technically no longer two-piece swimsuits. A regular bikini (i.e. not a variant) is defined as a two pieces of garments that cover the groin and buttocks at the lower end and the breasts in the upper end. Skimpier styles have narrow sides, including V-cut (in front), French cut (with high-cut sides) and low-cut string (with string sides). Other styles include a bandeau top - a rectangular strip of fabric covering the breasts, a top with cups similar to a push-up bra, and more modest bottom pieces such as briefs, shorts, or briefs with a small skirt attached.

A string bikini refers to a bikini swimsuit that is scantier and more revealing than traditional bikinis. It gets its name from the string characteristics of its design. Rather than featuring a full single piece bottom, the string bikini consists of two triangular shaped pieces connected at the groin but not at the sides, where a thin "string" wraps around the waist connecting the two parts. String bikini tops are similar and are tied in place by the attached "string" pieces. String pieces can either be continuous or tied.

It is claimed that Brazilian fashion model Rose de Primo created the first string bikini when she had to sew one with insufficient fabric available to her for a photoshoot. The first formal presentation of string bikini was done by Glen Tororich, a public relations agent, and his wife Brandi Perret-DuJon, a fashion model, for the opening of Le Petite Centre, a shopping area in the French Quarter of the New Orleans, Louisiana in 1974. Inspired by a picture of a Rio De Janeiro fashion model in an issue of Women's Wear Daily, they had local fashion designer Lapin create a string bikini for the event. Models recruited by talent agent Peter Dasigner presented it by removing fur coats by Alberto Lemon on stage. The presentation was covered by local television stations and the New Orleans Times-Picayune newspaper, and was sent out via the wire news services of the Associated Press and United Press International.

String bikinis are one of the most popular variations of traditional bikinis. A string bikini or thong is also a type of undergarment worn by both men and women. It is similar to but more revealing than a bikini. Women's string bikini underwear normally resembles the bottom of the string bikini bathing suit. Men's string bikini underwear consists of a front and rear section joined at the crotch but not at the sides. The tops of each piece join with either an elastic waistband similar to that found on briefs or to a thin piece of material or "string," leaving the sides exposed except for the string or waistband.
