Although women can sport the look, too, there is something almost iconic about seeing a man in a seersucker blazer with pants or shorts. Where a seersucker suit can sometimes get it wrong by being over-the-top, a jacket most often adds just the right touch of both warm weather casualness and up-one-notch style than going without.
Flat-front chinos in shades of tan and khaki or white are staples for the seersucker blazer, but well-tailored black pants or even jeans -- in black, blue or even white -- look great with a loose but not oversized blazer of any color combination. Light suede bucks also are the more traditional choice but black or brown leather with pants or boat shoes and sandals for shorts work well depending on the destination and activities, or lack of them!
And some added benefits of dressing up in dress-down seersucker are being able to worry less about ironing, sweating and dry cleaning; within reason, of course.
