The socks do run a little small so I ordered one size larger and they are perfect! My little girl LOVES them! It's hard to find cute animal socks of this style in larger sizes. She was still trying to squeeze her elementary school sized foot into her toddler socks. Not only do these fit, but they are soft and comfy too! She promptly relinquished the old socks upon putting on the bunny socks from this package :)
