I've never once worried about what my band mates wear (or not) on stage so why would I start worrying about it now? It's your life, do what pleases you. As long as it was not something that would draw us an obscenity beef with the cops, I don't care if you dress like peter rabbit or Gloria from down the block.
I've always resisted the wearing of uniforms, even as little as matching shirts or outfits. It's just not for me, including matching spandex body suits in fluorescent colors under black light, something someone wanted to do once for a frat party we were working. Thankfully no one else wanted to besides the guy who brought it up so we were saved from the drama. If they wanted to do it, fine, I'm all for it, for them, but not for me. I'm there to provide musical entertainment, not some kind of stage production involving props and costumes.
Don't get me wrong, my ability to put up with such BS is in direct proportion to the dollar amount promised. Pay me enough and I'll do a tube sock costume, but I'm mostly there to provide folks an excuse to ask someone to dance, not to hold them in my thrall for a few hours.
