Interesting also that he's wearing ghillie brogues.
I've seen other photos of him wearing them, but how often do you see the current royals wearing them?

Likewise the dicing on his hose.
Looks as though it came straight from a glengarry.
Haven't seen dicing like that on hose before. Then again maybe it just looks that way because of the photo quality and the fact that in my own mind it's red, white and black!
