Young Blonde Girl Strips Her Black Chemise On The Chair At The Window With Curtains

Until the late 18th century, a chemise referred to an undergarment. It was the only underwear worn until the end of Regency period in the 1820s, and was usually the only pieces of clothing that was washed regularly.
In the 1810s, the term came also to be applied to an outergarment. In Western countries, the chemise as an undergarment fell out of fashion in the early 20th century, and was generally replaced by a brassiere, girdle, and full slip, and panties first came to be worn.
Men's chemises may be said to have survived as the common T-shirt, which still serves as an undergarment. The chemise also morphed into the smock-frock, a garment worn by English laborers until the early 20th century. Its loose cut and wide sleeves were well adapted to heavy labor. The name smock is nowadays still used for military combat jackets in the UK, whereas in the Belgian army the term has been corrupted to smoke-vest.
A chemise, shift, or smock was usually sewn at home, by the women of a household. It was assembled from rectangles and triangles cut from one piece of cloth so as to leave no waste. The poor would wear skimpy chemises pieced from a narrow piece of rough cloth; while the rich might have voluminous chemises pieced from thin, smooth fine linen.
