I would like to purchase one of your leather peacoats (model 740L). I have a classic motorcycle racer jacket (model 141L) in size 54L which I purchased in 1991 and still wear regularly (although it's a little more sung than it used to be). I am wondering if I should purchase the peacoat in size 54L or perhaps 52L. I am 6'5" tall, weigh 250lbs, have 38/39 sleeves, and wear a 48/50 extra-long suit size. I generally wear between a 2XL and 3XL t-shirt. I would like to be able to wear a sweater under the coat but do not want it to be too roomy.
Thanks for your help.
