I have this in Slate (small) & just purchased the Orchid (medium). I think I prefer the size Small. For reference, I’m 5’4”, 150 lbs, size 6 and have a good sized rear end. Although I have never felt that this jumpsuit looked necessarily awesome on me, I do wear the it quite often, as it’s comfy and versatile. I get compliments on it nearly every time I wear it, so it must look better on me than I realize, so there’s that. I don’t find it particularly hard to finesse when taking on/off to use the bathroom, but do agree that a zipper would be just the thing to help this piece shine for non-jumpsuit wearers. I’m eyeing the yellow for my next purchase, as it looks especially cheerful.
