I purchased all the other styles as a small body adult but I was hesitant to get this color because it was way too childish ,but I saw it on sale decided to grab it , and I end up liking it the most! Life is funny @ times

Bigger than expected.
Size: Small, Color: Black/Cool Cats
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 .
