To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought a size 10 for my 8 yr old daughter and it fit just find with a little room to grow into. She loved how it felt and I loved that she won't be getting as much sun exposure with it on. We've only had it for about a week but so far it's been doing it's job.
