How about hose in your tartan colours, but with diamonds just in the cuff? This is a photo of the hose I had made to suit my Middleton kilt http://on.fb.me/kF9glZ. My tartan is very simple, but it's an alternative to full tartan hose. You might get a better idea of what it could look like from the the McCalls samples here http://bit.ly/iCHhnD.
