I too have been wearing yellow, or gold, hose with my XMtS kilt for some time and, I think, to great effect but, like Glen, I have no photos - yet! One thing that yellow hose does is to draw out the fine yellow stripe in the XMtS tartan, and make it a little more prominent.

As for flashes or garter ties: I usually wear the former in a mid-blue shade, or the latter in blue with blue and yellow fringes.

Take care,
Ham.
