Tweed for evening wear? - a call for pics

[M. A. C. Newsome]

John,

Re: the grey Prince Charlie, I saw that posted in another thread, and as I commented there, the cloth is not actually a tweed, but a worsted wool. This is especially apparant if you look at the close up pictures on the ebay pages.

Worsted wool has a smooth hand, but tweed is rather more course -- think of it with all the little fibers sticking out of it -- that's tweed. So my question is really whether a course fabric like this could ever work for more formal occasions.

I like the suit Rocky posted, though I cannot tell in the pics if it is worsted wool or a fine tweed. I think adding silver buttons to it would definitely give it a more formal look, but at the same time would take away some of the versatility.

How do we think Rocky's outfit might look if worn with a three-button vest and bow tie? Or perhaps a lace jabot?
