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.
Wore the sweater once, and the threads on both my wrist area started to fluff up. Could not get rid of it without ruining the sweater. So now the sweater has patches of fluff. Not sure what caused this but if it couldn't last 4 hours, not sure how the rest of the sweater would fair. Also the shirt I wore underneath it ended up having red cotton all over it, so that was not very fun lint rolling it all off. Nice fit but would not recommend based on its longevity.
