It depends how close you are & how much money you are willing to spend.
I remember a couple of years ago a friend of mine gave his best girl friend a Coach handbag for example.
As for my experience, the times I have had to give girls that were standard friends a BD gift I just asked my sister/mom to buy/recommend a med size handbag, not coach, tous or other high end, but from fossil or some other fashionable recognisable brand w/ a nice modern style/design which is easier on the wallet. All girls love jewelry, handbags & shoes, it all depends on what is your current state w/ the person.
