Just because it’s hot out doesn’t mean guys can’t look cool. This season’s bright colors, which star on shoes, chinos and shirts, make one of the best investments. Add to that groovy knit ties, the new-again summer suit (really!) plus slick bags and, dude, there’s no excuse to go on a style vacay this time of year.
