Dalziel - Apparently worn as trews by pipers of the band (*Can any ex-Greys corroborate this for us please?)

Royal Stuart - As kilts.

Unique among British cavalry regiments was that the Scots Greys fielded bagpipers. These bagpipers were initially formed by and paid for by the regiment because they were not authorised pipers on strength. At various times throughout the history of the regiment, there were pipers in the regiment, but these were unofficial.

While stationed in India in the 1920s, the regiment fielded its first mounted pipers. At the end of the Second World War, the British Army was contracting from its wartime strength. Despite the contraction of some Scottish Territorial and Yeomanary units, some of the personnel were retained by the army and sent to various other units. As part of this, the Scots Greys received a small pipe band from one of these demobilised units.

King George VI took a particular interest in the Scots Greys' pipe band. His interest was so great that he took part in the design of the band's uniform, awarding them the right to wear the Royal Stuart tartan.
