I'm always on the lookout for vintage Polo Ralph Lauren or Polo University Club sport coats, suits, and overcoats in size 38/40 reg. I like wide lapels with a traditional gorge height, so many from the 70s-90s are of my liking, along with the more recent "Garrison" model. I'm not looking for 100% cotton models of anything. A few styles I am searching for are below.
Black and white plaid or houndstooth
Double breasted navy blue chalk or pinstripe
