Cotton
Color: Blue, Size: Medium
I was impressed with the quality of this shirt. My son wears it to church. It is cotton. It washes and irons like the cotton shirts from years ago. I like cotton so much better than blends even though it must be ironed after washing. The shirt looks high end.

Light green is gray, but still good shirt
Color: Light Green, Size: Large, Color: Light Green, Size: Large
Light green is basically gray with a very slight green hue. Not a deal breaker, just not very green. Great fit and decently thick. Haven’t had to deal with many wrinkles and but not too think to be uncomfortable.

Perfect Fit & Feel This Striped Oxford Shirt is My New Wardrobe Essential!
Color: Blue, Size: X-Large, Color: Blue, Size: X-Large
I’m obsessed with this Men’s Long Sleeve Oxford Shirt! The 100% cotton feels incredibly soft and breathable against my skin, with a tailored fit that flatters my body perfectly. The subtle stripes, button down collar, and chest pocket give it that polished yet relaxed vibe. It’s wrinkle resistant, holds its shape wash after wash, and transitions effortlessly from office to date night. Comfortable, durable, and stylish easily is the best Oxford I’ve owned. I highly recommend it!

COOFANDY Men's Dress Shirt
Color: Denim Blue, Size: Small
I’m very pleased with this shirt—it’s actually the third one I’ve purchased from this brand. The quality is consistently excellent, the fit is great, and it truly lives up to being wrinkle-free. It looks polished and professional right out of the dryer, which makes it perfect for business wear. I’ve had such a positive experience each time that I’ll definitely continue buying from this brand.
