I bought these because they were a lot cheaper than the adult XS version. I'm 5ft 100lbs and the leggings fit just below my belly button but I can fold them a few times to keep them low. Can't attest to their warmth as I have a few months until I find myself in colder weather but they do fit. The length is perfect for me. They are a little baggy but the material is soft and thin perfect for wearing at home and don't care what people think. It can be a bit tricky under tight jeans. However, you can tell they are for kids as there is a chilli on the belt.
