Rather! I have seen everything from scarlet kilt hose, to argyle, to diced to any colour you want! ( I personally like a pair of tartan ones for the sake of tradition, I would love to see highland dress return to it roots more.) If the judge commetns on what type of kilt you are wearing, what jacket or shoes, or the colour of any of the above s/he is a pretty poor judge indeed. The people you play for aren't pick about what you wear usually (unless they ask for something specific) as long as it si celtic they don't care.
