Sens jersey sizing

Been getting into hockey more as I get older and have been to a few games this season. Looking at getting a Primegreen jersey from last season. I'm 6'4 about 230pounds. Was wondering what sizes people wear. I have a long torso, was looking at a size 56. Just don't want it to be to big, I'll always wear at least a shirt under it. I usually wear XL shirts.
