Costume Suggestions?

I’m looking for a costume to make for Dcon next year, something that will be easy and fun to dance in.
Slave Leia was my #1 choice costume for that in previous years, but it’s gotten so oversaturated I wanted to find something else. I tried Wonder Woman and Belle’s pink dress this past con – Wonder Woman just because that’s what I felt like wearing at the time (and it was not good for dancing, wearing metal in tight quarters is just not that great, you know), and Belle was just too warm.

So yeah, I’m looking for suggestions. I’d prefer it to be something fannish — an actual costume. Something swishy but that I won’t overheat in. Nothing I have to paint myself odd colours for or tape something to myself LOL
Ideas welcome! 🙂
