Snazzy shirt
Size: Large, Color: Black
Fits great & looks wonderful. Can be worn casually or for work. Very wrinkly, just toss it in the dryer and they will come right out. It's lightweight & cool.

Great shirts have to iron first
Size: XX-Large Tall, Color: Black
They feel great the material, they’re thin, the style looks good, the length to and below my waist is good. For the cost they’re good shirts and they’re definitely loose fitting, however they shove them in a tight bag so if you plan on wearing this straight away from delivery day make sure you have an iron ready every single collar and I ordered over 7 shirts comes folded over. Took a star away for the fact they don’t pack them how you would find a higher price shirt packed and typically wear ready.

Simple and nice.
Size: 4X-Large, Color: Dark Grey
Nice shirt. Light weight. It’s true to size and skin friendly because it is cotton.

Perfect!
Size: Large, Color: Beige
Cool, comfortable, with a little stretch. Comes out of the dryer wrinkle free (be sure to hang it up right after you take it out of the dryer) price was reasonable. I measured my husband's neck and it fit exactly as it should. Good length to the back of it too, which is sometimes a problem for my husband. Do not see any quality issues. Not excessively thin or too thick. Really, I can't think of any way to improve on this shirt.

Nice and light with superior softness!
Size: Large, Color: Black
Nice soft material and fits well. I also like the lightweight feel. Will most likely buy other colors in this item.
