What size clothes do a one year old girl wears?

A one-year-old girl typically wears clothing sizes ranging from 12 months to 18 months, depending on her growth and the brand's sizing. Some may fit into 9 months if they are smaller, while others may need 24 months if they are larger. It's best to check specific sizing charts from clothing brands, as sizes can vary. Always consider the child's comfort and allow for some room to grow.
