Ysatis by Givenchy.
I started wearing this after working for a rep doing some programming, and she gave me a gift pack since she was so happy with my work. There was a nice bottle of it in there, and it really worked for me; that was 22 years ago, and throughout my life I have had so many people tell me that when they smell that somewhere they think of me.
I remember hearing tips about leaving a dab on a mans lightbulb, or somewhere he will get a whiff of it in his home to make him remember you.
I never did that, only since carrying my purfume with me was something I never remembered to do! :)
