My 9 year old daughter often complained about being cold on the way to school and she prefers leggings. We had tons of 'warmer' GAP leggings and they just were not warm enough. She is about 60 pounds and 52 inches tall. She fits well in size M Irelia with room to grow. These really keep her warm and I ordered 4 more pairs . She wears them nearly every day now and I never hear about her being cold anymore!
