This is a really nice shirt, I ordered size XL, wanted to wear it and couldn't get my hands through the cuffs. Yes, the buttons have been undone. Too bad the size didn't fit.
Pros
PERFECT FIT AND COMFORT: Long sleeve shirt with a slim fit and button closure for a perfect fit and maximum comfort all day long. In addition, it is made of high quality and breathable fabric that keeps the skin cool even in hot weather.
Cons
It's a nice shirt and I like it, but it's too tight.
