It's got to be Jean Paul Gaultier, it's quite expensive but so worth it. I've never met a woman that doesn't like the smell of this and know many, including me, that LOVE it.
Ps, If you know one of her mates confide in her and find out what else will impress her, ie eating, films, flowers etc, but don,t go to overboard especially ifs its a 1st date, I agree with troot tho, be the perfect Gent, manners cost nothing but make a HUGE impression
