Dress code: "Black tie preferred, Victorian attire welcome"
Quote of note: "There are a bunch of professional Abraham Lincoln re-enactors out there, and we expect that a handful of them will show up in the full outfit with the beard and the top hat and everything." -- Carla Barry-Austin, media relations manager for Destination DC
Obama Pajama Party
Host: Carrie Fisher and friends
Venue: Ronald Reagan Building
Crowd: Supporters of a nonprofit group that gives sleep togs to needy kids
Dress code: "Pajamas or black tie / nightgown or ball gown"
Which means: Pinstriped pj's, bunny slippers under ball gowns, adult-sized footed jammies, and for the more fashion forward, may we suggest Dolce & Gabbana's spring 2009 pajama-party collection?
Quote of note: "Absolutely I'm wearing pajamas [to the party]! I wish I could wear pajamas everywhere. I spend a lot of my life in bed, which sounds a lot more sensual than it is. . . . I'll probably wear this sort of pale green nightgown that I got from a store in Paris called Sabbia Rosa -- on the Left Bank -- slippers and maybe even a velvet robe." -- Actress, author and event host Carrie Fisher
State Society of Arizona Inaugural Ball
Host: State Society of Arizona
Venue: The Historical Society of Washington, D.C.
Crowd: Expatriates of the Grand Canyon State and a handful of unhappy John McCain supporters
Dress code: Black tie or bolo tie
Which means: Feel free to swap out a traditional bow tie for the Western-style shoelace tie that's been the state's official neckwear since 1971.
Quote of note: "A suit is OK if you don't have a tux. We really don't want people to show up in jeans and khakis, but at this point, unless you show up nude, we'll probably let you in." -- Katie Vlietstra, inaugural ball chairwoman
Host: Chris "Ludacris" Bridges
