The plaid is twisted on the left shoulder with one loose end falling behind the wearer's back and getting tucked into the waist belt.
The plaid first appeared as a feature of Highland military dress in the British Army with the establishment of six independent companies raised in 1725.
These subsequently became the Black Watch, and the plaid continued as a conspicuous feature of the uniforms worn by Scottish infantry regiments.
In its original form, the plaid comprised about twelve yards of double-width regimental or traditional tartan, which had to be laid on the ground and rolled into.
[2] The plaid continued to be a feature of regimental full dress uniform throughout the 19th and early 20th centuries, although by 1914 normally worn only by officers, sergeants and pipers.
