Welsh Costume: Men's clothes

Rural working men generally wore clothes similar to those worn in other parts of the United Kingdom - a hat, neckerchief, shirt, waistcoat, jacket, breeches (the latter certainly until the beginning of the 19th century when trousers became popular), stockings and shoes. The main difference between men’s clothes worn in Wales and elsewhere, is that it is thought that they were more often made of locally produced woollen fabrics which, during the 18th century were often blue or grey. A few mountain guides wore eccentric costumes. The gentry normally wore the same as their peers in England but a few Welsh landowners had their clothes made of locally produce fabrics.
Many of the prints show men wearing breeches rather than trousers. Breeches began to go out of fashion by the early 19th century, but there is evidence that they were still worn in Wales by the 1850s, possibly for special events when traditional or 'Sunday best' costume was normally expected.
