A camisole is a sleeveless undergarment for women, normally extending to the waist. The camisole is usually made of satin, nylon, or cotton.

Historically, camisole referred to jackets of various kinds,^[1] including overshirts (worn under a doublet or bodice),^[2] women's négligées, and sleeved jackets worn by men.^[3]

In modern usage a camisole or cami is a loose-fitting^[4][5] sleeveless woman's undergarment which covers the top part of the body but is shorter than a chemise. A camisole normally extends to the waist but is sometimes cropped to expose the midriff, or extended to cover the entire pelvic region. Camisoles are manufactured from light materials,^[6] commonly cotton-based, occasionally satin or silk, or stretch fabrics such as lycra, nylon, or spandex.

A camisole typically has thin "spaghetti straps" and can be worn over a brassiere or without one. Since 1989, some camisoles^[7] have come with a built-in underwire bra or other support which eliminates the need for a bra among those who prefer one. Starting around the 2000s, camisoles have been known to be used as outerwear.^[8]

A variety of sleeveless body shaping undergarments have been derived from the camisole shape,^[9] offering medium control of the bust, waist and/or abdomen. Such control camisoles are the most casual of shaping garments, covering the torso from above the chest to at or below the waist. They look similar to tight-fitting cotton or silk camisoles, but the straps are usually wider, the hems longer, and the stretchy, shiny fabric provides a smoothing touch.
