Okay im 15 and in february my school is having a winter formal and I am sOoo stressed! The theme is Hollywood red carpet premier whatever the fuck that is

I would like a shorter dress. Preferbbly black or red and I really like gothic Victorian fashion. Also what shoes to wear? Are converse or combat boots okay? Also can someone find a link to a dress for me online? I'm really pale, blonde but I might dye my hair, really really skinny and flat cheated basically.
Also do I need a date?? I don't like a lot of guys at my school and they don't like me haha
