i swear by Thierry Mugler's Amen (or A*). makes females go MENTAL. seriously, i've had to like, fight the girls off wearing this stuff. pretty potent though so use sparingly.
Also just a note, it smells better on the skin than on a tester piece of paper.
another favorite is terre d'hermes. i only wear that one for work though.
another mention for Marc Jacobs Bang
awesome stuff.
