Commissioned by the Queen

[Fedgunner]

Matt Newsome's article on Solid Color kilts states:

The whole article can be found here: http://albanach.org/solid_kilt.htm

Of course this doesn't mean the Queen didn't commission a tartan for him, just that he seems to have usually worn a solid colored kilt. Too bad it wasn't brown (Zing!).
A cursory google search hasn't turned up any proof either way yet. Did anything you were reading cite sources that you could consult for more info on this legend?

It is the lack of scources that prompted this thread.

The upside is that now I have an excuse to obtain a tweed kilt!
