My measurements are:
Bust: 48in
Waist: 40in
Hips: 48 in
I ordered these in a size 3xl and they fit great! I have the hardest time finding pants and leggings, because my thighs are much bigger than my calves. Erring on the side of caution I ordered a bigger size just in case and to my delight these were perfect with wiggle room to spare!
They are thin, soft, and stretchy. The beaded part may fall apart in the wash so if you do throw it in the washer, make sure to throw it into a delicates bag. My only complaint is that the elastic band isn't sewn into the pants so it rolls around a bit but that can be fix with a few stitches.
