DISNEY’S ARIEL – LITTLE MERMAID – MY SIZE TALKING DOLL! SHE WORKS PERFECTLY AND COMES WITH EVERYTHING PICTURED SO SHE CAN GO FROM A BEAUTIFUL MERMAID TO A SWEET LITTLE GIRL DRESSED FOR SPRING! Dolls of this size take a toddler size 5 shoe. The new shoes she is wearing are a size 7. I believe these dolls originally came barefooted because they are mermaids, But I had this beautiful pair of new shoes I thought she should wear. I have put paper behind her heel.
