there shouldn't be too much shrinking even if i hot soak the shirt right?

thanks giles!

hey guys looking for some advice here.

my favourite shirt measures:
shoulders: 16in
length: 26.5in
chest: 20.5in
arm: 24.5in

this shirt is fitted, not too tight and not too loose.  i'm stuck between a XS and a S. what size do you guys think i should be getting?
