Well Made
Size: X-Large, Color: Navy Blue
When my husband put this shirt on, the women comment him on how he looks. I have to admit "He looks great in this attractive western shirt." The blue is a nice blue. He bought a black one, too and it is also very well made and nice looking. The sizing was perfect. It is wrinkle resistance, a great fabric thickness and comfortable. Definitely would buy him another if these ever wear out. It is a great value for the money.

Great Quality - Son loves it!
Size: Large, Color: Black
I ordered this beautiful Western shirt for my son for Christmas. He loves it so much he wears it once a week. The quality is excellent. The fabric is relatively thick, but not too thick - a nice, sturdy fabric. The embroidery is absolutely beautiful! It looks even better in person. The large fit him true to size, like all his other size large men's button up shirts. There are no loose threads or flaws in the stitching. It looks and feels expensive - well worth every penny of the $40 price. It has held up well in the wash. There has been no fading or shrinking. It is now March and it has been washed once a week since Christmas. (Please note - I don't put it in the dryer. I hang it to dry.) I highly recommend if you are looking for a fancy Western shirt.

Got more than I paid for and am so impressed!
Size: Medium, Color: Burgundy, Size: Medium, Color: Burgundy
Absolutely stunning! Great material quality and embroidery work. Every bit the same as those you'd buy at Boot Barn or other western stores for $70 to $100. I'm so impressed!! I purchased these for my son's band (4 shirts for 4 band members) and the band members love them. This saved me so much money. I'm so happy with them and plan to purchase more of these in different colors and styles. The men said they're comfortable and love wearing them.

Size 3XL was correct. Fitted to arm length.
Size: 3X-Large, Color: Khaki
Most important- I was hesitant on this as a 3XL from the USA is very different from a 3XL from China. But very glad to report size was perfect! Arm length fitted nicely. So recommended. Very nice product- especially for the price!

Impressive quality!
Size: Large, Color: White
The model really made this shirt stand out for me. I ordered it, and I too looked good in it! The material was soft, of quality and had superb wrinkle resistance. It was also nice amount of thickness, preventing unwanted and awkward transparency. You know, when someone can see through your shirt. ;) I ordered a size large and it fit perfectly. The color I opted for was white, and it’s classy and complements my skin tone. Planning to buy more in the future.
