Agree in the main with Jock Scot (White NO) but being a bit of a colour freak, I like to at least wear a colour in my hose that is in the tartan, or that does not jump out of whatever the kilt colour is, so that the kilt remains the main visual statement.
I like to start off with hose up but in hot weather and hiking mine often scrunch down and flashes removed ...more so when in hiking boots.
But kilted.. enjoy your choice...if you feel comfortable go for it!
I was once told by someone that If a person says "you look good"... then you are ... but if they say... "I like your socks" (or shirt or other choice other than your kilt)... then that is the dominant thing they notice and not YOU... Get the idea?
