Goth ballerina halloween costume?

for halloween i want to be a goth ballerina, im wearing a black leo, black tutu, white tights, black ballerina slippers (flats) , and black leg warmers. I want to have my hair in a bun, and than im going to have scary goth make up. At my school (higschool) we are dressing up in our costumes for a donation and wearing them to school (we wear unforms) so do you think i would offend anyone with the goth makeup ? And would this be okay to wear to school ?
