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....

FABRIC BLEEDS! I washed this before wearing it and one more time- then I washed it with some other items and it STAINED IT AND COMPLETELY RUINED IT! Quality is terrible! Fabric is THIN! Do NOT waste your money! And yes I did wash as directed by the manufacturer.

I order two deferent Western Cowboy Shirts and both of them fits perfect and true to size. I am 5'7 and 206 pounds and perfect fit, I love black with brown and brown snaps, and the other black shirt has blue snaps. both shirts are nice and warm for the winter season; I most like Stitching good Quality and very Comfortable and worth the money.
