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.

I think it runs big. Otherwise good. Poor packaging though.
Color: Light Blue, Size: Large
I ordered a Large. I am 5’ 9 1/2”. Fit, 170lbs (athletic/slim build). The Large was noticeably too big. Looked “sloppy”, like it fit once and then I lost a bunch of weight. That said, the material/weight was very nice. This is a nicely made, casual blazer. Will look good with jeans/khakis or dressier pants. REALLY nice for the price (I got it on sale, 50% off ($31.99) though. Maybe a push, or nicer ones for $60/70, but I’d still say a good value. Packaged in a bag as people have mentioned. I’ve returned for a medium & will probably have to take to the dry cleaner immediately to have pressed, but still worth it.
UPDATE: returned for a size M. Much better fit for my size. This one was packaged nicer too. Still in a bag, but folded nicely enough to wear right away. I’m planning on buying more colors.
