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.

Horrible quality and service
Color: Navy Blue, Size: Medium
The quality of the jacket is horrible. After the jacket was returned unused. The company kept trying to say it was never returned. Was able to provide Amazon with the tracking from UPS showing it was delivered and signed for. Amazon issued the refund. 4 months later now, the company is trying g to charge me again for the jacket. Was able to prove again to Amazon the item was signed for when returned. Amazon is issuing a refund again. Do not trust this company with your credit card. They will continue to try and charge you months later.
