Lydia is small, fragile looking girl with long blonde hair and blue eyes. She is very skinny and tends to be quite pale as she is not really a fan of playing outside much given that she tends to burn easily and doesn't like many outdoor activities to begin with. Until recently, Lydia dressed in clothing that some would call "babyish" but Sophia pointed out to their mother that maybe she should dress a little more age or people might make fun of her and now she dresses in a way more typical of eleven year old pureblood girls.
