I ordered sweatpants for my daughter instead of leggings because she is tall and slim. The leggings look like capris on her to get something small enough for her tiny waist. I had the idea of going with sweatpants instead so we could go full size to get something fairly logarithmic but use a drawstring to tighten the waist to fit her waist size. We get these pants. Full size is larger and they are barely long enough. And the drawstring is sewn just for beauty - it has no function.
