camisole (n.)

1816, "short, light garment with sleeves," formerly worn by women as morning-dress, from French camisole (16c.), from Provençal camisola "mantle," diminutive of camisa "shirt," from Late Latin camisia "shirt, nightgown" (see chemise). In modern use a sleeveless undergarment for women (1900). In late 19c. it generally meant "strait-jacket, a restraint for lunatics."
