I'd have thought it would be a sexy school girl outfit with big thick rimmed glasses and maybe your hair up like:

look online there's plenty on there.

You dress like me!! Lol idk!

You will need a low cut top, and definitely a tie. Wear suspenders with shorty shorts, and high heels. Hope this helps you become a sexy nerd!

knee high socks, pigtails and a mini skirt

get some braces (the kind that go over your chest and hold up your trousers, not in your mouth), a bright bra, a white shirt, unbutton it, a short black skirt and long white socks and black heels :)<3

super short pleated kaiki skirt with suspenders, a white blouse that is unbuttoned a few extra buttons, converse, glasses and your hair curled in big curls

Thats unusual but whatever. Wear those huge glasses, and a short skirt. Wear a white blouse, maybe a little see-through.
