Khaki service dress, for home service, was introduced in 1902, at first having a stand-and-fall collar closed at the neck. In 1912 the lapelled version was adopted that required a shirt and tie, also khaki. This is the longest-lasting military garment ever, as it is still worn in the 21st century as no.2 dress. The shoulder straps can be seen, but the rank insignia was put on the cuff, here denoting second-lieutenant. Later in the war, the rank stars were put back on the shoulders. Scottish regiments’ jackets were cut away below the waist to show the sporran, but apart from that it was similar to the service dress jacket worn by the rest of the army.
The Sam Browne belt had, by this time, developed into the single shoulder strap on the right shoulder, providing support for the sword on the left hip. This officer does not wear a sword but he has a leather frog for it to slot into. The broadsword was taken to France at the beginning of the war but was found to be more of a hindrance than as a useful weapon. The kilt and undress sporran would have been covered with a khaki apron in the trenches. His hose and boots have khaki gaiters. Where other infantry regiments had a khaki forage cap, the Highlanders retained their blue glengarry caps.
