The British Army has long included Highland regiments, hardy units recruited in Scotland– that in some cases were established long before the British Army was. Kilt-wearing regiments included such storied outfits as the 42nd Foot/Royal Highlanders/Black Watch, Cameron Highlanders, Gordon Highlanders, the Seaforth Highlanders, and the Argyll & Sutherland Highlanders.
Many of these regiments still issued the knee-length pleated uniform kilt for field dress as late as 1942 and Highlanders sent to France with the BEF went to the Continent in 1939 wearing their traditional uniforms.
Today the pipers of the Scots Guards and the Jocks of the Royal Regiment of Scotland as a whole still wear the Type 1A Military Kilt on occasion (although the latter includes several lowland regiments that have been amalgamated) and to keep you straight on how to do that properly, check out the hilarious instruction from CSgt Benson, Master Tailor of 2 Scots, below:
