Hello all, I need help with sizing. I think I'm good with size 31 for this jean but little hesitant that it would stretch too much. I see the waist measurement for size 31 as 29.6, that's 14.8 across waist w/dip. I usually wear jeans that measures 16~16.5" across waist w/dip. Does anybody know how much of that 14.8 will stretch out to be? Thanks in advance.
