So I thought I wasn't going to my uni faculty ball this year due to a, uh... shortage of funds; but my dad out of the blue offered to buy my ticket!
So now I have a ball in ten days, and absolutely no dress to wear.
Given that I couldn't afford the ticket, you can imagine what my dress budget is looking like... maybe $40?
I also have pretty much one day to sew something if that's the route I go.
While I want to look nice, fancy finishings and whatnot aren't really necessary. I can cut corners

As long as it lasts till midnight...
So - suggestions! What can I whip up in a day that will make me the belle of the ball? Is there a tute here you can suggest? Is there a really nice, very easy pattern you've used to make a formal gown? Any 'cheat' ideas (like, uh... I don't know - dye and embroider a full-length satin slip...)?
I'm going to check out the local vintage clothes store tomorrow (in the hope of just finding some hilarious 70s lurex number that I can just wear outright, but I think everything may be beyond budget).
My only requirement is that it be tea-length or floor-length.
