thats a hard desicion!!!
but i think that the goth girls look really cool!!!
the goth girl with the black hair called Anthrax (Dee Plume)the other called Ebola (Sue Denim). the electro girl with the black hair called Neon the other called Ultra.
i wish you and your friend lots of fun !!!

Although my scream name is weirdly stolen from the electro girls Ultra and Neon lol i would say the goth girls cause their costumes look better
:)hav fun at ur social

I think you should be electro girls, they're called Ultra and Neon(she's the one with dark hair).

hey why not go for old gregg and the naan bread :) lol that should make an impact!
