A smoking jacket is an informal men's style of lounge jacket originally intended for tobacco smoking. Designed in the 1850s, a traditional smoking jacket has a shawl collar, turn-up cuffs, and is closed with either toggle or button fastenings, or with a tie belt. It is usually made from velvet and/or silk.
Originating in the 1850s, The Gentleman's Magazine of London, England, defined the smoking jacket as a "kind of short robe de chambre [i.e. a banyan], of velvet, cashmere, plush, merino or printed flannel, lined with bright colours, ornamented with brandebourgs [i.e. frogs], olives or large buttons."[1]
The smoking jacket later evolved into the dinner jacket, essentially a dress coat without tails, following an example set by Edward, Prince of Wales (later King Edward VII) in 1865. The smoking jacket has remained in its original form and is commonly worn when smoking pipes and cigars.
