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 mistakenly had the idea that Amazon's offerings of proprietary clothing products would be similar to Costco's - better than average quality at lower than average price. I tried the Amazon mens shorts, but was disappointed with the quality - not terrible but fabric seemed flimsy compared to some other brands. So I "upgraded" to Goodthreads, but sad to say am even more disappointed. The fabric wrinkled badly on first wearing and has stayed that way. Back to Costco, Dockers or Brooks Bros on sale!
