The girl is a prostitute, mate. She's dressed like a prostitute, so her thinking is of a prostitute. A prostitute thinking girl becomes a prostitute when she starts acting like one (dressing first; after that drinking and the sex for money). And one more example that has to make you sure that the girl's prostitute: What would you think of a man dressed like a woman and acting like a woman? Is he a gay or just normal man with unswitable clothing?
