Love this color brown! Very nice shirt!
Size: XX-Large, Color: Brown, Size: XX-Large, Color: Brown
Purchased for my husband for a fall wedding! The fit was great and it was wrinkle resistant. The material was soft and comfortable. It was warm enough for a fall wedding but also breathable and he looked amazing in it! I LOVE the color!

Vary comfortable
Size: X-Large, Color: Brown
I really like these shirts. I got one
in the brown color because I didn't have a nice brown shirt. They fit so well and they have a very smooth feel, almost like silk. My wife said that I look great and that's what matters most. She also likes the fact that they are wrinkle free so there's less ironing. 😃
I now have five different colors, and they all fit perfectly, and I love the way they look and feel. Thank you

Great Color Dress shirt
Size: Medium, Color: Light Green
I purchased this dress shirt for my husband when he needed something to wear as a wedding guest. My dress had a bit of turquoise in it so we thought this would be a good compliment to what I was wearing. We ordered his normal dress shirt size and this was a perfect fit.My husband is slim and it was nice that this shirt wasn't boxy at all. The neck was a comfortable size and the arm length was spot on. He has nicer, more expensive dress shirts of better quality but this seemed to work out just fine for what we needed. The color was a nice shade of turquoise.. not too green and not too blue so we lucked out in that area also. We did wash this before wearing. My husband didn't complain about any stiffness/scratchiness etc.the whole day! I would say anyone wanting to purchase this shirt, that they will be pretty happy with the overall fit and comfort.
