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.
This is a nice, light-weight, sort of slim fit t-shirt with decent stitching quality. The medium size fits as expected for my 5'10" 150lb body, but it's a close fit that looks good if you aren't overweight. Size up if you are between sizes or like a looser fit. The sleeves are short and close-fitting for a stylish look. I washed it and damp-dried it on medium heat and there was no shrinkage. There's nothing fancy about the shirt, but it's a nice, basic, well-made tee and I like it a lot.
This is a comfortable shirt -- the cotton is very soft. It's a little smaller than I would have expected (I got the Medium), especially in the sleeves. If you have big upper arms, I'm not sure it would work for you.
