lots to say...but I really need costume ideas

So, I have lots and lots to write about, but this sinus infection is causing me to operate at about one-tenth my normal speed, so I will have to do major writing at a later date.

Anyhow, I am planning of going to the Fencesitter's Ball in SF this Friday, and I need costume ideas....anyone, anyone...Bueller?? I need to wear something in which I can move and dance in with relative ease and which will not require me to purchase much (I am awfully broke these days).

I have PVC skirts and tops, black tights, black boots, black velvet dresses, and random dance costumes to work with....Anyone have any great ideas?? My head is so fogged from this illness I can barely do basic arithmetic, so I am not at my creative best here. Any help will be greatly appreciated!!
