This has become one of my favorite shirts. The fit is excellent, and it's versatile enough to wear tucked in for work or untucked for a more casual look.
I ordered an XL. For reference, I usually wear an XXL in most T-shirts, and the XL in this shirt fits me perfectly. The length is just right whether it's tucked in or left untucked.
I've probably worn this shirt around 10 times over the last few months, and it's held up really well. I wash and dry it at home—no dry cleaning—and I haven't noticed any significant shrinking. The sleeves also roll up nicely and stay in place.
The fabric is lightweight and breathable, so it's comfortable even on warmer days. It has a subtle sheen to it that's hard to capture in pictures but gives the shirt a really nice look. Someone once complimented it and described it as looking "buttery," and I thought that was actually a pretty good way to describe the finish.
The fit is comfortable without being baggy. It's loose in the right places, layers well under a sport coat or jacket, and doesn't bunch up or ride up throughout the day. The stitching has also held up well, and I haven't had any loose threads around the buttons. It does not wrinkle like some of my other shirt and also irons very well.
The quality exceeded my expectations, especially for the price. I liked this shirt enough that I ended up buying it in white and dark green as well, and I'd definitely buy another if more colors become available.
