Try to ask innocent personal questions, like finding out if she has a boyfriend and is single. If she is single, find out what she does for fun, such as partying on the weekend or after work. If she is interested in you, she will be willing to talk about personal matters. If she is not interested in you, then she will say she has a boyfriend or clam up. If she is really flirtatious, just go for it and the worst that can happen is rejection. But if she is a flirt, then she knows how to handle getting asked out. If she has a boyfriend, just say "he's a very lucky guy!" - That way she knows you are respectful of her and not sour, but also playful and able to be the backup guy if she dumps/cheats on her boyfriend.
