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.
Just received mine today and really like the fit and quality. But take heed, the reviews are accurate. I'm 5'4" and 133 pounds--I have a wide rib cage and a mom belly but normally wear a medium. I ordered the X-Large and it barely fits.
