Perfect for and a great suit coat for the price
Amazing fit and a very decent cloth suit. Shipping was amazingly fast and received with in a day. It's a true size and fit. Great value for money and looked perfect. Strongly recommend this to all. Right out of the bag.. Needs a bit of ironing but perfect.

Great jacket. Good price.
Purchased for dinner on a cruise. The fit was perfect. Lightweight for the tropics. The little white pocket square can be folded down if you don’t like it. I took off a star because the color was darker than pictured. It is more of a denim blue instead of a light blue.

Runs big
Really thick and hot. It also just was very big and boxy. Definitely order a size down if you plan on buying it
