new year's eve: stuck going to the same party as your ex boyfriend

This is my most dreaded situation, you find out that you're going to the same new year's eve party as your ex boyfriend. Obviously you clicked attending first and he followed suit. I bought this dress as a present for a girlfriend's birthday. We've now dubbed it "The Lucky Dress." Just make sure you don't eat that extra spring roll at the party when wearing this though. stockings / dress / bag / shoes / headband
