“I really like these pants :) Having said that, I'm not sure what 'Lightweight' refers to... they are neither lightweight in actual weight or in tummy control. I'm between a 16 & 18 and bought the 2XL, I actually wish now that I'd bought the 3XL as when I wear the pant I wear them for a full day (walking) and can't wait to get them off and put regular joggers on.”
