As a bestfriend of a blonde bimbo I see this all the time and no exactly what works.

Women seek attention, so flirt with her friends then buy them all a drink, or three, offer to take them somewhere fun sometime, like boating, or a casino, or a party, whatever you can pull out of your pocket. In short the following works, handsome face, nice clothes, nice watch, pay the tab, be fun, flirt with her friends. Most important thing is paying the tab, they aren't into a lifetime of diamonds at first all they want is fun on your bill.
