Now it's the right time to start wearing that unconstructed jacket of yours or buy a new one.
An unconstructed jacket looks the best with chinos, jeans or white pants, but for the brave ones; I recommend giving it a try with a pair of shorts. With shoes I would probably go for brown suede or leather.
They sell these bad boys in every imaginable color now a days; navy and white are classics, but light pastel colors are cool too.
