In 1942 the Making of Civilian Clothing (restriction order) was passed. This prohibited wasteful cutting of cloth, and set a list of restrictions that tailors and dressmakers had to work to. Dresses could have no more than two pockets and five buttons, six seams in the skirt of a woollen dress, two inverted or box pleats, or four knife pleats. No unnecessary decoration was allowed.
