I'm not 100% sold on dressing up tonight (it's going to be cold, my feet will hurt, etc.) but luckily I don't have very much in the way of shining metallics and sequins, so the selection process will likely be not that difficult.
In the meantime, I dredged up some looks from New Years' past. That 2010 looks is SO painfully 2010.
2010: Zara shirt, vintage bandage skirt and bag
2011: Vintage dress, belt, necklace, J. Crew headband
2012: Anthropologie pants, Madewell blouse, vintage shoes
