The style
Overall the suit is good. The picture shows white buttons, but came in black. I have to swap out the black for all white.

Failure at every step
Item sent was wrong size, missing pieces and used! Not happy. Thankfully Amazon made it right because Coofandy dropped the ball completely. Think twice before ordering from this vendor.

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.
