Comfortable and well made.
A well-made, cotton shirt, suitable for casual wear. I like to wear this in the summer untucked with the sleeves rolled up over a colored t-shirt. I found the tail of the shirt to be a bit too long to wear untucked without looking odd, so I had it shortened; now it fits perfectly. It is made of cotton, so an iron is mandatory if you don’t want to look like you slept in it, and it will get some wrinkles as the day progresses, but that’s cotton’s nature. I liked it so much I purchased a second one.

Nice shirt, runs a tad small.
Fit Type: Slim Fit, Color: Light Blue/Indigo, Plaid, Size: X-Large
I guess that slim-fit is not for my hubby and this is a little too fitted across his pooch belly. But he loved the blue color plaid. Fits well elsewhere. If you're not a flat-stomach, dont bother with slim-fit I guess.
