Surely four months isn't that long...
I have a Highwayman in size 40 and it fits good. I have a Aero Cafe Racer in a 44 and it is snug. I was told that the fit is more like a Cafe Racer so I was thinking of going to a 46. I am 5'9" and fluctuate between 185-195 lbs. I have a wide back though. I am wondering if they take in consideration the thick shearling when sizing it.
