I have Givenchy for women (the one Liv Tyler is promoting). It's light and much sweeter than I would normally go for, but sometimes it's just right.
I'm a fan of wearing men's fragrances. Ten years ago I used to wear Joop for men.
I just smelled Givenchy's Pi for men - love it! Sophisticated and light, vaguely fruity and woody but very understated. Just bought a small bottle off eBay. I'm too fickle to blow that much money on a whole bottle - who knows what I'll fall in love with next?
I will say I've remained a fan of Narciso Rodriguez for her.
