What A Find! Unbelievable Quality and Price!
Special Size: Standard, Size: Large, Color: Plaid-light Blue
I can't believe the quality of this shirt!! I ordered the blue checked one for my husband for a costume. The price was right and I didn't expect much, as it was just for a costume. It came packed into a little box, which I figured showed it would be super thin and cheaply made, but didn't really care as only needed it for one time. Woah!!!! I opened the box and was absolutely floored by the quality and heft to the material. It is crazy. I don't know how they get this shirt into that box, but it is baffling. This shirt is of high quality, with all the seems sewn well. The fabric is every bit as good as the brand of oxford shirt that costs 3 times the price of this one. My husband goes between medium and large. He takes 16" neck in dress shirts. We ordered the large and it fits well. Has a little room, but not in a too big type of way. I washed it once before wearing, and it washed well. Not much shrinking at all. It ironed very easily without a problem. Yes, it is 100% percent cotton. Because of the quality and fit, I will now order additonal colors. My husband loves this shirt. This is an excellent buy!!!

Great shirt!
Special Size: Standard, Size: X-Large, Color: Dark Green
My partner loves this shirt and is very particular. He likes the green color and that it is cotton. Bought more colors from this company. Runs true to size.

Amazing quality 11/10
Special Size: tall, Size: XX-Large Tall, Color: Aroyal Blue
It’s an amazing quality shirt. White is bright, not a single thread, all folds are just perfect. I can’t believe I got this quality for this price 🙌

Not too bad for the cost but could be better.
Special Size: Standard, Size: 3X-Large, Color: Navy Blue
I like the shirt. It fits well and color is as described.
Main reason for 3 stars is that they do a lousy job with sewing on the buttons.
