... to be in her knickers and Bra?
It's the one where she rips her tights, is sick, smudges her make up and then goes out. Where they say 'you wouldn't start your night like this...'
At the very begining she is sat on her bed ripping her tights, then stands up and is weang knickers and a bra. Seems to be no reason why they should have to have her virtually naked when she could easily rip her tights with her skirt and top on and having her near naked doesn't add anything to the message of the advert.
I'm no prude but I wonder why it was thought o be necessary?
