Dessous

Lingerie is a term for women's fashion undergarments. It derives from the French word 'lin' for linen. While the term in the French language applies to all undergarments for either sex, in English it is applied only to those women's undergarments designed to be visually appealing or erotic, typically incorporating materials such as Lycra, nylon (nylon tricot), polyester, satin, lace and/or silk and not applied to functional cotton undergarments.
