It’s no longer a no-no to wear a smart jacket with a pair of jeans. Once, only ponytailed balding directors would be seen in that garb, but with a little taste, you can look great with a smart blazer and your fave denim. One fine example is the Fink Herringbone Field Blazer which is cut slim and long. It has a 3-button placket with button flap chest and side pockets.
In the detail, it has one-button cuffs, 2 inside pockets, a double-vented back as well as being fully lined. Good news is that it’s machine washable so you don’t have to keep running down to the dry cleaners with it. It’s a cotton/polyester mix and going for a very reasonable $88.00 (about £45)
