She should do Playboy; the money's good, and it's not as if she's ever going to be able to do anything much with her brain or personality.
Thing is, she's not well known enough to be considered for Playboy. If they did a UK version then maybe, but I doubt she'd be considered otherwise. If she's got a hankering to take her clothes off, she'd be better advised to negotiate a deal with FHM or, most likely, Maxim.
She'd probably still show the same amount of skin that she would have in playboy and she'd earn a sizeable amount of money.
