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.
Based on the other reviews, I ordered a large, but they aren't as tight as I like my leggings to be. They still fit, but if I lose a few pounds I'm afraid they'll be too loose. They feel great though and I'll be ordering more of them in medium, and in different colors. I'd recommend these.
