Love it . Ingot this for my 6 years old . But she is petite and I keep a bigger size becuase they say was bigger . But no my daughter is skinny and 50 pounds . That size was twice bigger on her 😳... so is inconsistent the comment and size. My daughter is really petite . She normally used size 4/5 .

Adorable and quality!

Size: Small, Color: Blue Cat

Adorable and excellent quality. Daughter didn’t like it at all though and it does run on the bigger side, but I’d still recommend. It’s warm, thicker not cheap material and color is vibrant and pretty!
