I bought this for my son to wear at his band concerts, and it’s been perfect. He’s about 5’8” and 155 lbs, and I got him a men’s medium—it fits really well with a comfortable, true-to-size feel. The quality is excellent: soft, lightweight, and breathable, with just enough stretch so he has the flexibility he needs while playing trombone. It also looks really sharp on stage.

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.
