My daughter is 47 pounds and 46 inches tall. She is 6 years old. I bought size 7/8. I bought it in the fall for the winter-spring season. It's big but not obscene on her. We have 6/6x and it really fits her, but not when I wear a long sleeve shirt in winter. She has the best length on her torso. My daughter is average height, she is not very tall but has a longer torso. I like the french toast line, they don't shrink much but fade over time.
