It depends on the brand. Try on as many as you can. I'm 6'1", 220 and wear anything from a 50/60 to a 46/56. -Tom
im 6'4'' and weigh 280 but im still skinny i wear 54 in alpine stars i can sqweeeeeze into a 52 but the chest to waist is to short i needed a little longer so i went with the 54's edit.... i just woke up an old post sorry about that its been awhile since i was forum trolling.... i have to knock the dust off!
