I'm 5'6" and I ordered an xl. I received xxl-xxxl. Outer package says xl but inner tag said a much bigger size. I was bummed but tried on anyway. Surprise. They fit. I've bought jeggings like this from as seen on tv ads when they first came out years ago. But those are alittle tight. These fit great. They got past my ankle so taller girls, you don't have to fear about these being high waters. The fleece on the inside is nice. The seams all in tack. There is no strange gusset which some brands make and I hate those cuz you'd always have to wear tunics in case you bent over.... No one wants to see a gusset it looks like pantyhose. The stretch is great. I imagine this will shrink a bit after a wash or two . Air dry or low heat should be okay. The rear pockets are real but shallow. I love these with boots! . They don't take that much room. Remember, these are not stretch jeans or modal colombian jeans. These are leggings with a fake jean like print. No real zippers or buttons. I got the dark smokey color. I'm 145 lbs. I normally get a size 8 or 10 in ck suits. Mt waist is able 30 and the fullest part of my hips and around my rear end is about 40 inches. These are great for the fall or cooler weather. You don't sweat in these. I don't find these to be sheer. If you buy to small, then yes it could look thin in places. Don't get hung up on what the sizing says as it will make you feel bad. China sizes are different. But when you get the right fit on your body, you'll feel great. I only wish this had a but of tummy control so just wear the correct undergarments.
