I liked this shirt so much that I thought to write a review immediately raving about it. Then I saw the comments about pilling. So now, I'm not so sure. I was going to keep both colors I got (Heather Grey and Heather Navy), but the pilling might mean I only keep one. I can say that it's a very hot, humid day right now, yet I feet cool with it on. The medium was a tight fit, and the arms were just a little short with the thumbhole. So I sized up to a large. It's a loose, straight fit. The Heather Silver is as it appears in the photo, but the Heather Navy is more of an indigo than a navy as shown in the first photo. The blue is closest to the image of the woman next to the part about using Coats thread (half way down the description etc.). I'll report about the pilling after I've worn it. But, I don't have high hopes given my experience with a skirt in similar fabric purchased a couple months ago. That said, after months of looking, this is the only plain (logo-less) crew neck shirt with thumbholes that also has a higher neck that I've found to date. The rest I've found have scooped out necklines. And as I'm looking to use this for sun protection, a higher neckline was important.
