They are not suitable for little girls. These socks are one size and I would not order them under 10 years old. They even fit me in size 39, and my daughter (5 years) wears them over the knee like "thigh socks" π€ͺ, very cute, she loves them and that's the main thing. The quality is excellent, they appear durable and soft - just like the photos. 5 stars and highly recommended!
