I have a few favorites, the classic Polo, JHL, Eternity--for men of course and a great new cologne on the market: L'eau Bleue D'issey. Leau Bleue gets lots of comments.
I use a perfume oil called Egyptian Goddess. It's a very faint musky smell that you have to be really close to me to smell, and I don't wear it all the time.
I like it when guys wear cologne, but only if it's really faint. It's nice if I'm sitting across the table from him and can't smell it, but then I smell it when I give him a hug. That's perfect! My husband uses the Gilette Cool Wave after shave gel; it smells good, yet it's more casual than cologne.
