My daughter is 5 but has outgrown the smaller sizes on this brand so I bought a size 6-8. They fit her all winter and don't look too big when she gets dressed. They could have made the top a bit shorter to make the size more suitable for tall kids (the top gathers at her waist because it's so long). They are very cute and I love the extra ankle dots. I wash them inside out as the dots will pucker but like other tights from this brand they are well made and warm enough for winter.
