Okay, so I'm going to an erotic poetry reading tomorrow nite (where I'll actually be reading onstage so I need to look good...) and I bought a white sailor uniform shirt that comes down *just* long enough to be a minidress. Here's the only problem: since it's a shirt, it has no waist.

I'm temporarily living w/ friends and my sewing machine is in storage so I can't take the side-seams in and add darts... I bought a belt, but the extra material when I belt it in still looks baggy and funny.

So, here's my question: How can I take this shirt in by tomorrow nite without the use of a sewing machine???

Any help would be GREATLY appreciated! Thanks in advance!!!
