As a final insult, I thrifted a couple more things. A HF casual long sleeve dress shirt for $5 (very rare in Australia, this is the first one I'd ever seen in all my time thrifting) and a sports coat for $10. The SC is a recent wool/silk blend and is what I consider to be a very good fit OTR. Sure, it's some department store brand, but it's very much a case of cheap and well fitting looking better than expensive and ill-fitting.
On the plus side, I did sew on a button and cleaned my wife's boots.
I think I can go for the rest of the month without falling off the wagon. Again.
