Cape

A cape is a sleeveless outer garment, which drapes the wearer's back, arms and chest, and fastens at the neck.

Capes were common in medieval Europe, especially when combined with a hood in the chaperon, and have had periodic returns to fashion, for example, in nineteenth-century Europe. Roman Catholic clergy wear a type of cape known as a ferraiolo, which is worn for formal events outside of a liturgical context. The cope is a liturgical vestment in the form of a cape. Capes are often highly decorated with elaborate embroidery. Capes remain in regular use as rain wear in various military units and police forces, in France for example. A gas cape was a voluminous military garment designed to give rain protection to someone wearing the bulky gas masks used in twentieth century wars.

In fashion, the word “cape” usually refers to a shorter garment and “cloak” to a full-length version of the different types of garment, though the two terms are sometimes used synonymously for full-length coverings. The fashion cape does not cover the front to any appreciable degree. In raingear, a cape is usually a long and roomy protective garment worn to keep one dry in the rain.

In full evening dress, ladies frequently use the cape as a fashion statement, or to protect the wearer or the fine fabrics of their evening-wear from the elements, especially where a coat would crush—or hide—the garment. These capes may be short (over the shoulders or to the waist) or a full-length cloak. Short capes were usually made of, or trimmed in, fur; however, because fur is less accepted as a fashion accessory in modern times, other expensive materials are substituted for it, with an opulent lining and trim. Typical fabrics used are velvet, silk and satin. Capes are still authorized as an alternative to the more utilitarian trench coat for U.S. Army officers in mess dress, formal evening uniform.
