Great fit
Size: 17" Neck 37"-38" Sleeve, Color: Blue Frost
This was a gift for my husband. Fit is great. He's about 6'1" and weighs ~200#. Washes nicely as well. A good purchase

Comfort& Quality
Size: 20" Neck 35"-36" Sleeve, Color: White
Excellent shirt.
Ordered for a Risky Business bar crawl and the fabric was so much nicer than the other two options I ordered. It is packaged so nice with pins and feels luxurious (great if you’re giving it as a gift.) It comes wrinkled from being folded in the packaging, but i steamed it and then it did not wrinkle while driving or sitting throughout the night. It’s nice and light. Only downfall is there is no pleat in the back.

Nice shirt.
Size: 17.5" Neck 35"-36" Sleeve, Color: White
It fit perfectly and looked very nice. However, it was much thinner than I thought. And when you wash it, get ready to iron it. This is not a permanent press shirt. It is not wrinkle resistant. I would not buy it again.

Casual Crew Neck Summer Shirt
Color: Denim Blue, Size: XX-Large
Ordered the dark blue. It fits great and looks wonderful on. Very comfortable! Good value, and feels well made. The fabric is just right – not too thin, or thick. I wore it with a navy blazer and beige pants to an outdoor event (shade and sun) and was totally comfortable.
