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 14 for my 12yo thinking it, at worst, would be a little big on her. She is a petite girl. The suit was so small that it barely fit her 10yo sister. I would have returned it, but I had it shipped overseas and the cost to return/refund was more than the actual swimsuit.
