Very cheaply made
Size: X-Large, Color: 02khaki
Not happy at all … this shirt did not arrive as displayed. It’s pictured as two tone giving the impression that it’s a dark brown fabric on top and a different light brown fabric at the bottom… it’s a thin one piece shirt with what appears to be a spray paint top. Very cheap looking

Great shirt for the price!
Size: Small, Color: 01black
Nice for cowboy look! Shirt was just what I needed, it had a little stretch, and not to heavy. I wore it to a party , and the price was reasonable!!

Just an imprinted fabric, nit Western. AVOID
Size: Large, Color: 02khaki
So disappointed. This is a cheap polyester shirt without inserts or western detail. It’s just all part of the fabric …not even a separate piece of fabric …so IN THE PICTURE it looks like a really cool Western shirt. NOT! It is just a junkie polyester job. Save your money.

Country wedding guest shirt
Size: XX-Large, Color: 01black
My best friend had a country themed wedding and I got this for my husband. It fit perfectly. True to size. Looks exactly like the pic. The material is sturdy so we will have to find another reason to wear this, but it’s a keeper
