Bought on Ebay. Can't remember brand, but it's a wool and mohair mix. Was NWT and retailed for 500$ or something, been packed away since NYE.
Followed with a silk PS, pre-tied bowtie and shirt (not the one in the picture, but it's a normal cotton, hidden placket shirt)
Paid 60$...no alterations.
Wish the button stance had been a bit lower, and armholes higher, other than that I'm pleased with it!
