I think some of the fan art concepts are better than the new costume. I'm actually surprised that they went with the bright colors and roller disco look.
I think it works, the one on the right looks like a butch Conan. Everything's grey/brown these days, and anything from the old days gets desaturated by 50% and is called modern.
They're channeling Erin Gray from Buck Rogers in the late 70's... Personally, I think they should do Dazzler instead and get it over with. You know that's what the network execs really want to see...DAZZLER! She's a rocker! She dresses like a hooker! It's sort of like American Idol meets Glee meets Wonder Woman!
According to Wikipedia, Jubilee created "fireworks of explosive plasma", while Dazzler "converted sound vibrations into light and energy beams". I wouldn't have known the difference without looking it up, apart from Dazzler wearing roller skates.
