Lingerie is a category of women's clothing, including at least undergarments, sleepwear, and lightweight robes. The specific choice of the word often is motivated by an intention to imply the garments are alluring, fashionable, or both.

Lingerie is made of lightweight, stretchy, smooth, sheer, or decorative fabrics such as silk, satin, Lycra, charmeuse, chiffon, or (especially and traditionally) lace. These fabrics can be made of natural fibers like silk or cotton or synthetic fibers like polyester or nylon
