I seem to remember either somewhere on one of the XMTS threads or on the Cameron-Seaforth Highlanders web page that the proper hose and flashes to wear (military style) were khaki hose and red flashes. Like McMurdo, I also got the garter ties from Scottish Tartan Museum. That being said, the khaki hose and red garter ties were on top in my sock drawer and they just happened to show up in the pix. I think they look better with McMurdo's Gordon than the MacKenzie.
