Piped brim panama + seersucker suit = all good fun. Adding in the fancy spectators & the bright bow tie as well... just a bit too ebullient for me I think. A darker bow tie with non-spec wingtips and I think would come over more smoothly. Either that or a navy long necktie with those fancy spec.
In retrospect, my C & J Maltons in chestnut would have been a better fit with the rest of this rig - for next time, then. I don't think that the tie is the problem - the shoes don't work with the seersucker as I had imagined that they would.
