When you're going out dancing, it's usually not a good idea to wear something that constricts your breathing.
Corsets, no matter how cute they look, should be laced so that you can breathe. Otherwise, it'll mean an early night.
Oh, and Sparky? (Like he'll ever stumble across this but still...) You and your girlfriend can dance! I don't care how easy you say it is, I still can't dance like that.
But ya'll still suck for leaving early.
