Some of these shirts arrived in perfect condition and looked flawless. ONE DID NOT!
Size: 20" Neck 37"-38" Sleeve, Color: Cameo Blue, Size: 20" Neck 37"-38" Sleeve, Color: Cameo Blue
Three of these shirts arrived in perfect condition and looked flawless. The sizing is fantastic: it matches the listed measurements and fits a curvy man’s figure perfectly. ONE SHIRT, however, did not arrive in perfect condition. It looks like they took it out of its original packaging, damaged it on purpose, and put it in a trash bag in very poor condition to ship it. Someone in management at this company should pay close attention to how the shipping and courier staff handle the company’s products, as this will have very negative consequences and generate unfavorable reviews for the company and its revenue. Look at the shirt on the far right!!

Very well made Oxford casual shirts.
Size: X-Large, Color: Sky Blue
I've ordered 8 of these Button-down collared, long sleeved Oxford shirts in eight different colors. I'm 6', weigh 195. And have a 44" chest and fairly broad shoulders. The XL give me ample room, plenty of shirt tail to tuck in. And are well made. The shirts have a nice soft feeling to them. If you wash them with like items, and dry them likewise, taking them out before the cycle ends and hanging them. You won't have a single wrinkle. The shirts are true to color, and true to size if you follow the size guideline. These are not tailor fit, but regular fit shirts. Fabric quality seems very durable and well made. There is no smell when receiving the shirts. No more so than buying a shirt at a retail store. They do come in a vacuum bag. The shirts are a little heavier than a poplin shirt and can be worn year-round. These are great casual shirts for jeans and a sport coat, or slacks. I like the quality and the colors. I also like the thickness of the shirts. All of the shirts I've bought, black, blue, etc, have white buttons. Which makes them more of a casual shirt. But well worth the price.
