Nice shirt, great price
Size: Large, Color: Royal Blue
Very nice shirt. Has a soft, flowy (?) hand to it. Not starchy like a lot of oxford button-down collar shirts. Second one I’ve bought. Nice

Great shirts.
Size: X-Large, Color: Black
I have 10. These are great, stylish shirts especially for the price. I usually wear between size L-XL slim fit (Banana Republic). I’m 6’ 200 lbs medium athletic build and L fits perfectly. With a quick press, they do not wrinkle easily. I get plenty of compliments.

Runs large, not slim fit
Size: Medium, Color: Green
The shirt definitely runs large like all the other reviews say. I usually wear a large, but the medium fit much better. The shirt is definitely not slim fit though.

Great fit and look
Size: Medium, Color: Grey
Husband loved it! Great fit and he said it was comfortable. Can be worn untucked or tucked in pants. He wore it with jeans and a blazer untucked for a graduation party and looked perfect for the occasion.
