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

Comfortable and stylish
This has been wonderful. My son is a game show host and has to wear a blazer to work on game days. He throws this in the back of his car when he’s done and it’s went through a lot and still holds its shape. The colors look great and it’s comfortable. He says it doesn’t feel heavy on and is easy to take care of.
