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.

Cheap and nice shirt
Fit Type: Slim Fit, Color: Pink/White, Buffalo Plaid, Size: Large
Beyond the actual color of the shirt is not as described, the shirt is fit to size as well as comfortable. It is not wrinkle free treating but the condition is acceptable after drying in dryer.

Surprisingly decent for the price.
Fit Type: Slim Fit, Color: White, Size: X-Small
XS slim fit has the right amount of stretchiness. Not too thin and wrinkles iron out well. Needed it for a last minute professional photo. Looks like a more expensive shirt when worn with a jacket.
