Vintage Tuxedo Jacket

This vintage tuxedo jacket is labeled as a size 42 Reg. However i am a 42 regular and this jacket is small on me i'd say it's closer to a  40 reg. I am wearing this jacket in the pictures. I am 5' 10" and 185 lbs. I hope this information better helps you make your size determination. The jacket is in excellent shape. There are no stains, holes or rips.
