The Jonathan Jacket from Billy Reid is the perfect piece to transition into the Spring/Summer months with little effort. Made of a heavyweight chambray gaberdine shell, you won't have to do a bunch of layering. The most impressive detail is in the keyhole button collar that is rarely done on a blazer, but BR pulls it off. Italian-constructed, this jacket will always be in style. Available at Unionmade for $595.
