As well as being a Kilt and Scotland fanatic, I'm also a trekkie and I asked some of my fellow fans on one of the Star Trek themed boards I post on why Scotty only wore his Kilt with his dress uniform. They said it wasn't functional, but then I remembered that I thought I had seen a pic of Scots wearing kilts in battle during WWI. So does the Scottish navy wear kilts with their regular uniforms, or just for dress occasions?
