    Quality Shirt!
    Size: Medium, Color: Black Orange
    A good quality shirt with an embroidered pattern. The fit was right on the arms and shoulders but ran big in the waist area. The fit really depends on your build. The price was fair for this quality, highly recommend!

    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....
