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.
The size of this particular piece was small. My daughter wears between an 8 and a 10. I ordered the 10 for her to have for camp. It was too small and show way too much of her chest. I sent it back with an exchange for the 12, and it was still too small. I returned it with a request to credit my Amazon account, but they changed it to return funds to my bank account.
