Here you go!
EDIT: Well crapola. That's probably not what you are looking for.
I do know the measurements are garment measurements and not chest measurements. So if the full circumference around your chest is 46, then a size 46 may be too tight.
If you are not sure about the size and worried it may be too tight, I'd just go with the next size up to be safe. IMO, Better the jersey be a little larger than too small.
