Good material. Not too thin and it's rigid
Size: Small, Color: Black Red
Perfect. I'm 5'9 skinny dude and I normally wear a size medium. I took back the medium and got a small and it fits me perfect.

Runs Small
Size: X-Large, Color: Black_a
I own several embroidered Western shirts by known manufacturers, including one purchased on Amazon. All are XL, and they fit fine. So I ordered XL on this shirt. I can wear it, but it's not a good fit or very comfortable. Specifically, it is a very slim cut - much slimmer than the dimensions given in the description state. So if you are a slim guy, no problem - order your usual size. If you are stocky, as I am, go up a size. In every other way, I really love the shirt - beautiful embroidery, very nicely made. I love the contrasting colors inside the collar and placket (inside of the snaps). I have re-ordered in XXL and hope and think this will fit fine. Not to figure out how to return this from the Philippines....
