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 guess the size is about right for a medium. It's really too tight and actually way too small for an iX. MUCH too small. I decided to wear it anyway but was very uncomfortable. It is not only too tight (even for a stretchy thing) but the armholes are too small! The lace around them chafed underarm so bad I had to go home and take it off. After laundry, I will attempt to cut the lace off so I can (choke) wear it... or maybe I'll just chuck it.
