Great Quality Vest
Great quality vest versatile for all occasions. I personally felt it ran a bit tight (I ordered a large and felt like I was sucking in a bit the whole time) but I think an XL would have been too big. Overall impressed and happy with purchase.

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.
