I find good old shirts, with the looped closure for the collar button, all the time at thrift stores. Watch out for moth holes though: Pendleton wool must be very tasty. Another thing to look for are Pendleton three-quarter winter coats, the tweedy, quilt-lined ones, with leather buttons. I have a brown one that projects a very traditional "country" look, and I get vigorously complimented every time I wear it. It's exceptionally well made too. Then there are the traditional/professorial-looking tweed blazers with elbow patches--I look for those, but don't have one for myself yet. And the very "Western" blazers, with the curvy (sometimes suede) yokes, and suede patches...I think you need a longhorn hood ornament on your Caddy to wear those. And then the hats. There are great old Pendleton tweedy Trilby-like old-man hats, plaid, herringbone, etc. etc., with jaunty feathers. Don't have one of those yet. Good God. Am I a vintage Pendleton freak? I have lots of other, very different types of clothes, I swear.
