Silk blouse

A blouse (English pronunciation: /blaʊz/, /blaʊs/, or /bluːz/) is a loose-fitting upper garment that was formerly worn by workmen, peasants, artists, women, and children. It is typically gathered at the waist or hips (by a waistband or belt) so that it hangs loosely ("blouses") over the wearer's body. Today, the word most commonly refers to a girl's or woman's dress shirt but can also refer to a man's shirt if it is a loose-fitting style (e.g. poet shirts and Cossack shirts). Traditionally, the term has been used to refer to a shirt which blouses out or has an unmistakably feminine appearance.

The term is also used for some men's military uniform jackets.

Blouse is a loanword to English from French: blouse means "dust coat". It possibly was brought back from their travels by French Crusaders. They moved on their armor a so-called "p(e)lusisian shirt", a blue-colored gowns to the dust, which had its name from the Egyptian town of Pelusium. The derivation may also be from "wool", blouso "short wool" and blos, blouse "deprived, naked" taken off (Provençal dialect). It is first officially noted in 1828, from French blouse ("a workman's or peasant's smock"), of obscure Occitan route.

Blouses are historically a cask style, mostly mail-like garment, that were rarely part of the fashionable woman's wardrobe until the 1890s. Before that time, they were occasionally popular for informal wear in styles that echoed peasant or traditional clothing, such as the Garibaldi shirt of the 1860s.
