Traditional Grown Man Shirt
Size: Large, Color: Light Grey Vertical Stripe
Great cotton, classically-style button down shirt for guys not wanting anything slim fit, this shirt size is legitimate. It’s a nice heavyweight cotton shirt. I don’t think I’d say it was wrinkle resistant but it doesn’t take much effort to press this garment.

Softer and Larger than Expected
I was a bit wary of this shirt because I had only purchased 100% cotton ones in the past. My first impression out of the package was how soft the material felt. I was very impressed because it usually takes many washings before oxford cloth shirts get that soft. When I put it on, I discovered that there was no noticeable difference made with the small amount of stretch fabric woven into the shirt. I suspect that there would be some give if I wore the shirt as a tight fit, but I prefer my shirts loose, so it wasn't an issue. I found that the shirt was larger than other same sized shirts I've received from Amazon in the past--bigger is better than smaller, but if you are looking for a close fit, you will want to be conservative in the size you order. I didn't realize until I'd been wearing it for a while that it lacks a pocket, I went to put my glasses in my shirt pocket and there wasn't one!

Looks great
I got this to make a memorial shirt for my grandmas funeral. I was worried it may be too hot but the fabric is thick and breathable. Easy to heat press on. Looks great! I actually want to buy another

Good fit, stays tucked.
A little long to wear untucked, but long enough to stay tucked through the work day.
