Bought size large, 8-10, which is supposedly for weight range 67-84 lbs. My son weighs 57 lbs and they fit around his waist and hips perfectly but were a little snug in the thigh (which we managed by excessively stretching the material). My son has averaged sized thighs, his height is 49" tall. Other than that they are fine.
