ADANIKIWomens Yoga Pants with Pockets Straight-Leg Loose Comfy Modal Drawstring Lounge Running Long Active Casual Sweatpants

I wear a 18-20, would a XXL fit??

Can I cut the bottoms or do I have to hem?

Do these pants have any metal on them like a grommet in the drawstring area? I need to get something for hip x-ray without metal.

List fabric in description? modal is processed with chemicals that many people are allergic to and the ftc will not allow to be labeled natural!
