I have a few pairs of seersucker pants, and they are less tailored and more "deconstructed" (?) than my seersucker suit pants, so I'm going to assume yours are along similar lines. I always envision seersucker pants with a navy polo shirt, but for some reason, I think a white polo shirt or a white buttondown w/ the sleeves rolled up ends up looking the best. As for shoes, I used to wear tan C&J loafers w/ a white buckskin vamp or plain white bucks, but now I pair them with simple tan loafers, and am pleased with the results . . . sockless whenever possible.
