I can see sizing being off a little, but the person modeling these must be a really thin teenager. I always wear a medium in champions and these are small in every dimension. Forget the nicely drapped appearance. These cling to my thighs, which while not small, aren't huge either. They also seem much shorter than the picture and with the waistband turned down would sit a good ways below my navel.  Since I got them mostly to work out at home, I won't bother to return them, but they are much too small to wear to the gym. In my opinion this is not a woman's size but a "juniors cut."
