I had to take lessons from a professional "Life Coach" to learn this, but when shy women flirt, they are likely to...
... move into your "personal space"
... tilt their heads forward, as if nodding
... make eye-contact by looking up
... smile
... make open-palm gestures
A more assertive woman is likely to introduce herself and ask for your name.
A woman playing mind-games will likely try to attract your attention while pretending not to.
In other words ... it depends.
