Shortening the hem, definitely. Be SURE to ask them specifically for "original hem" - it will cost more but will be worth it. Don't know about tailoring the waist etc.; there are so many combinations of cuts out there, I usually just try on until I find one that fits.Is it possible to have denim jeans altered? Specifically, have the waist, maybe the seat, taken in an inch or so. How about shortening the hem? Is there a good tailor in the boston area who can work with denim?
