I am 67" tall, 208# 47" bust, 42" waist, 48" seat, 31.5" inseam. After going back and forth between whether I should get the XXL (because I realized these were a loose fit) or 1X plus (because that's what size I was per the chart) I got the 1X plus in regular because the last thing I wanted was for this to be tight. I mostly wanted these for snowshoeing and winter camping, not skiing or boarding.
I pulled them on over sweats to try them on. They were comfortably loose in the chest and waist and comically large in the hip and thigh. The legs were way too long even after I put ski boots on to see how that worked. With the boots I wear for snowshoeing it just wasn't happening; I'd be tripping over my cuffs.
I think the seat zip is brilliant. I LOVE the Ginger color and these are very well constructed. However, I am sending them back and I'll use the credit to get a shell instead of trying another bib. I can't be confident a size down in the short version would suit my purpose either and unfortunately I can't keep trying and sending back outlet items. All of my measurements fit the chart for 1X plus so my advice would be that unless you really want that super baggy look or live somewhere where you will be encountering extreme cold and need to layer profusely; size down.
