Whilst it is common to see the Dukes of Rothesay and Edinburgh kilted I cannot remember seeing (m)any of either the Duke of York or the Earl of Wessex so attired.

But as it is a highland games event one would hope that the Earl does attend kilted and I am sure that this would be very well received.

As for William and Harry, they currently appear to be lost causes for kilts, don't think I have seen kilted pictures of them since they were little.

William may well have to think again when he becomes Prince of Wales and Duke of Rothesay because he will then be more subject to protocol than he is now.
