HELP! I NEED A DRESS!?

Okay, so here's the story. There's a dance tomorrow, and tomorrow is also the second last day of school. I'm switching schools next year, so this dance is my last one at my school and it'll be really memorable if I go! Problem is- I don't have a dress. I can't go shopping but I know my friends can today. They said if they see something, they could try to get it for me, but it's not too reassuring. ALL the dresses I have I've worn for either a dance or another school event! I REALLY REALLY REALLY NEED A DRESS! HELP!
