<human>: I got a tuxedo for an incredible discount at a formal wear store going out of business for my university's only formal event.  But the event only had 500 tickets for 4000 undergrads, and seeing as its being held at the library of congress those tickets sold out less than 1 second after going on sale online.  So now I've got a fresh tuxedo and nowhere to go.  I know dc is the capitol of gala's, fundraisers, etc so there has got to be some formal events around here that I can get into for free or for a minimal cost.  So anybody know of anything going on, or perhaps a place to figure out what events are happening in dc.

Could you distill the essence of the text into 1-3 sentences?
