While the term in the French language applies to all undergarments for either gender, in English it is applied specifically 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. It is commonly pronounced in English with a faux French pronunciation (such as LONJ-er-ee in British pronunciation or lonj-er-AY in American pronunciation).

The concept of lingerie being visually appealing was a development of the later nineteenth century. Up through the first half of the 20th century women selected underwear for three major purposes: to alter their shape (first with corsets and later with girdles or bras), for reasons of hygiene, or for modesty. Women's underwear before the invention of the crinoline was often very large and bulky. As the 20th century progressed underwear became smaller and more form fitting. In the 1960s 'controversial' lingerie manufacturers such as Frederick's of Hollywood begin to glamorize lingerie and the idea of lingerie having a sexual appeal slowly developed.

The lingerie industry has expanded in the 21st century with designs that double as outerwear. The French refer to this as 'dessous-dessus' which basically means innerwear as outerwear. The boutique Faire Frou Frou, which is an antiquated phrase meaning "show it off", heralds this philosophy by categorizing lingerie as an accessory with details such as straps and lace trim that should be layered and shown as part of one's outerwear.
