Is this ok to wear to the dance?

So my high school, I'm a freshman, is having a dance tomorrow, it's not like a big one, Homecoming Prom etc, just a dance. I was thinking of wearing a black wife beater tank, gray skinny jeans, black low top Converse, a studded belt and maybe my silver batman belt buckle. As for my shoulder length reddish brown hair I was just going to shake it out a bit and leave it down. Is that like apropriate for RVHS's "Color Fusion Dance" (because we just have to be different and not have a Sadie Hawkins)
