Yep, its headed back tomorrow. I'm debating to pull the trigger on the 42 and have it sent in or just wait until I can go to London later in the year and try them all on to make sure I get the correct fit.
I just bought the J24L size 44 from RMC London.
Measurements are as follows:
P2P: 21 in
Sleeve: 26.5 in
Shoulder: 18.5 in (back measurement - difficult to get accurate measurement from front due to fur collar)
Length: 26 in (from base of collar to bottom of jacket)
I'm 5'10in / 179lbs (fit)...
