I'm always happy to see the Duke of Rothesay in a kilt~ he wears it very well, looks very comfortable and often wears a brown leather sporran with black regular brogues, just to show it can be done. I must say though, I prefer him a touch less formal than this, like when he's in tweed (It's difficult to tell from the small pic but that doesn't look like tweed to me). He looks a little bit half-and-half~ you could cover his lower half and never know he was kilted.
