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 was looking forward to this working for me, but that's one of the downfalls of ordering online. The size wasn't right for me (very large chested) even though I went by recommendations. I thought about sizing up after trying it on, however the material wasn't great either. It was kind of scratchy and it was uncomfortable. I'm also not sure it wouldn't show through regular tshirts.
