I'm between a 2x and a 3x, so I ordered the XXXL and holy smokes these are huge. Not only are they really big, but they're crazy long for a petite size. I'm 5'5" and they drag on the ground. I can maybe get them off the ground by pulling them right up under my boobs. Heck, I could probably pull them up over my boobs - they're big enough!
Not worth returning them for the $13. I've been wearing them around the house a bit. Thought maybe I'd try wearing them out, but the first time I wore them my daughter, who has zero fashion sense and never notices what anyone is wearing, took one look at me and asked "Why are your pants so big?"
