I still use the woolrich set my dad bought in the 50's, nothing like a vintage Pennsylvania tuxedo to blend into the deer woods.

Stone ... awesome mate !
   
Mine is my Dads too !

George google Woolrich . Their web comes up. Buy on line. Very expensive 110.00. Also says Campmor has them. Alot of Folks get theirs from Good Will Shops, Salvation Army Shops and even The Big Web Used item site. I bought all mine at Meltzers. They told me I was one of the few that still like the stuff. Go Figure. Bought my pants and 2 shirts there.

Check the auction site, search for men's plaid wool shirts or jackets. You can usually find some really nice stuff for under $25.

Don't go by the listed size on anything you find there, check the measurements because a lot wool clothes made a trip through the washer and drier and a large will often be closer to a medium.

I checked the measurement arm pit to arm pit, sleeve length and distance from the collar to the bottom hem of one of my shirts that is a little big on me. If I see one for sale I like with the same measurement I bid on it.

My last acquisition was a red and black plaid Melton jacket from the 50s that looked like new for $18.

I haunt the local thrift stores as well but wool items are few and far between in the south where I live.  

A word of caution, I have heard the one should take any clothing bought off the auction site directly to the washer or dry cleaners as soon as you open the package. There is a slim chance the item came from a house with bedbugs.

A bit of history --- the name "Buffalo Plaid",
it originated in about 1850. Seems that the designer had a small herd of Buffalo--- thus the name --  Buffalo Plaid--   )
It still works  !
Red and Black remains the most popular color
Green and Black seems to be popular in Maine, Vermont and NH--- NY Hunters mostly wear Red and Black ---  IN Scotland  the different Clans worn differnt tarten plaids to identify themselves--
