As MOR says the jacket names are mostly the creations of individual manufacturers to add a frisson of glamour to the article. Jackets such as Crail, Kenmore and Braemar are simply called after towns of that name, none of which have any tangible connection to the jacket named after them. In fact Crail is a small fishing village on the coast of Fife where kilt-wearing of any kind would have been unlikely in the extreme. The Montrose is also known as the Military doublet because of its similarity to the style worn by some 19th century regiments, although it is much simpler without the heavy gold braid ornamentation. Other jackets, again as MOR says, are loosely based on 18th century costumes and the tashes or Inverness flaps are thought to be a hangover from similar flaps on suits of armour.
