Raw denim, waist expanded, to hem?

Hi guys, I bought a pair a Gap raw denim a few months back, fit nice and snug without the need for a belt and then over the course of a few months I now need a belt plus it bunches up around back and crotch. I have only done a warm water soak when I first bought these and that's all I've done. My question is, should I get them hemmed in the waist now (about an inch) or should I wash them first, then hem? Will the effect on the waist be the same in the end or will the wash shrink them "for good"? Thanks, Charles
