The D.C. “retro-forward” socialite group Dandies and Quaintrelles hosted a bike-oriented Seersucker Social over the weekend — a summer-themed followup to the popular Tweed Ride in the fall. DCist photog maxedaperture has the participants in all their tandem bicycle–riding, finger sandwich–eating, croquet–playing, refreshment—swilling glory.

Waivers in hand, seersucker-clad riders assembled at Meridian Hill Park to ride through Rock Creek Park to Hillwood Estate, Museum and Gardens in Northeast where, for $20, participants enjoyed picnicking, music, and anachronism. If one of the boons of seersucker is that it allows you to go out in terrifically hot weather, then the seersucker socialites couldn’t have asked for better weather to show off their duds.

So, question. When did D.C. get so fey? Don’t get me wrong: There are a lot of people I love in those photos, I dig super-social hangout Marvin as much as the next guy, and I’ll keep buying Worn Magazine so long as they keep putting half-dressed Adrian Parsons on the cover. But when, exactly, did it happen that fashion wasn’t exclusively the province of D.C. music? When did it break off and start moving in another direction (notably, backward in time)?
