I'm attending a Daughters of the British Empire Christmas Tea this Saturday, serving basically as an usher (and decoration for pictures). I'll be in my Scottish National kilt, which I think has nice Christmas colors, dark grey Argyll and waistcoat, and day sporran. My question is how to combine my hose, flashes, and tie.

I have the option of my green hose with red flashes that compliment a solid red tie, which I've worn before. That works, but in the spirit of the holiday I bought some red hose and green flashes. Once they arrived the green in the flashes is horrible and clashes not only with the kilt but also with anything else I might put with it. I have some black flashes that wouldn't look out of place with the red hose, but what do I use for a tie with that combination?

If all else fails I could go with my existing combination, but I was hoping to add a bit of Christmas color with the red hose. I'll be in basically the same outfit for Christmas eve, and am ordering a properly colored green tie with matching pocket square; my talented wife is going to make flashes out of the pocket square for me. But as for this Saturday, what to do?
