Darker than advertized
Size: Medium, Color: Grey, Size: Medium, Color: Grey
The grey is much darker than advertised. Additionally, jacket came with two buttons and not one as advertised. I ordered a Medium and it fits a little big. No inside pocket, which isn't the worst, but I really like inside pockets.

Nice for the price
Size: Large, Color: White
I needed a white jacket for a specific event and this is actually pretty good quality for the price. I was quite impressed. I’m only going to wear it one time, but I think you’ll be pleased with what you get for the money.

Know your body type.
Color: Navy Blue, Size: Large
I really liked the look and the buttons when I ordered it but I wound up returning only because I have to have a slim or fitted cut for any shirt to look good on me. This shirt did not hug me in the sides and looked like I was wearing someone else’s clothes. Nice shirt and good quality but it didn’t fit me personally. I did consider having it tailored but the cost of doing that was almost as much as the shirt.
