Go for lady gaga style(s)!
just wear your normal clothing
Just go out in Burberry underwear. Nothing but. You'd look sexy then!
I been to a few chav themed parties and usually the girls end up wearing trackie bottoms with white trainers, a jumper or hoody with their hair tied back in a pony tail with big hooped earring.
There is no way a Chav theme exists.
I've seen chavvy people in very short tight dresses and uggish boots... and hoops!
shave your head? seems to be chav culture for both the males and females of the species- it attracts the opposite sex for mating purposes apparently, or so I read
snort skirt, hoop rings should be enough while retaining your dignity and looking fhhhhhhhhhhhhckn fine.
