Not bad for the money
Color: Blue, Size: X-Large
Not bad for the money, BUT, not high quality fabric (KINDA wrinkles easily, but Ironed nicely.. Stitching was decent.. Only washed one time (inside out and in cold), so it's kinda early to fully rate, but I will not over -wash it...For a musician, it's kinda nice ...Might buy a couple more for the stage👍

Sexy Shirt!
Color: White, Size: Large
My husband loves it. He says it’s soft and very comfortable. Flexible with his body but not tight at all. He’s a size large, 180# with welding pipes! He’s a welder by trade so his biceps are decent, this shirt doesn’t strangle them. He looks amazing in it and it wears well and comfortably under a suit or sports jacket. True to size and color.

5/5 Stars
Color: 01-black, Size: Large, Color: 01-black, Size: Large
I absolutely love this black cowboy shirt! The first time I put it on, I could feel the quality. The material is comfortable but sturdy, and the embroidery on the front and sleeves is just beautiful. It gives that true Western vibe while still looking classy and modern. What I really like most is the fit — it’s sharp and clean but still gives me room to move and stay comfortable. I paired it with my boots and belt, and the whole outfit came together perfectly. I’ve gotten so many compliments wearing this shirt, and it definitely makes me feel confident and put together. Whether I’m dressing up for an event or just want to rock a casual cowboy look, this shirt never misses. It’s definitely one of my favorite pieces in my closet now!

Too loose
Color: Black (Retro Rose), Size: Small
I really like this shirt, but unfortunately it is way too loose for a size S. It looks like a XL. A shirt like that should be tight.
