BUTTONS LIKE A SMALLER SIZE. GOOD QUALITY.
DESIGN IS EXCELLENT. QUALITY IS FINE. I WEAR A LARGE, BUT THIS VEST, IN A LARGE, DID NOT ALLOW ME TO BUTTON ... AS IF IT IS A MEDIUM FIT. WILL RETURN, BUT IT IS A VERY GOOD VEST OTHERWISE.

Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart. I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.
