Aja, I don't know if you are male or female so I am suggesting possibilities for both sexes (none of them easy to construct on such short notice, I'm afraid).

Female: Scarlett O'Hara whipped up a festive dark green ball gown from her living room drapes for a scene in GWTW! Marilyn Monroe looked pretty sexy in the dress was wearing when she stood over the street vent in "The Seven Year Itch." Man: How about Tarzan. Very simple costume, you could probably manage with a bath towel as a matter of fact. You might consider Jom Joad, in the "Grapes of Wrath." Kahki pants and work shirt. I'm sure these suggestions will probably reach you to late to help, but I tried.
