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 order a pack of size small shirts. One of the shirts is labeled an XL rather than a small, and on the shirt that is a small the stitching is incorrect on the shoulder making the sleeve cap begin half way across the shoulder blade rather than at the end of the shoulder. It is clear that it is due to poor construction as the one sleeve cap is placed correctly. If you're looking for plain t-shirts I would suggested trying somewhere else, it's not worth it to order these.
