As snow swirled into the District on Saturday during the longest government shutdown in history, invitees gathered in tails and ballgowns for the annual Russian Ball at a glitzy ballroom at a private downtown social club. Despite chilly foreign relations between the United States and “Mother Russia,” politics seemed far from guests' minds as they partied late into the night with fellow descendants of Russian royalty.

Year after year, the white-tie gala continues to hold a unique place in Washington’s social calendar, offering a theatrical evening of vodka, Rachmaninoff and extravagant ballroom dancing. Despite the formality of the setting, everyone is friendly as can be and social posturing remains virtually nonexistent — a rarity on the D.C. party circuit. First-timers stand agog at the sheer spectacle, and return guests are warmly embraced as family. Nasdarovje (cheers) to that.
