Here is my Orvis Murphy's Irish Pub Vest made in a thick Donegal Tweed, I obtained a few years ago, sadly it does not get to much use so I may let it go soon.
Still a fantastic versatile waistcoat, that will last for ever I should imagine due to it's construction.

There's an Old West clothing site that sells lots of lapeled waistcoats, as well as other old-timey clothing. I can't vouch for the quality, though. And I don't have a link because I'm writing this on a different computer that doesn't have the link stored. Does this site ring a bell with anyone?
