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 orgered a size 6 and that is the XXS!! It was tiny :) I had to return. They need to update the size chart to indicate that the numbered sizes are not even close to typical american sizes.
