Delicious scents (be it food, perfume, flowers...) make me happy, so I love a good perfume on others.
I thought of this thread today when a man walked into the bakery who wore an ocean-y perfume with some spicy notes. Very intriguing and seductive. I didn't follow him home, but did keep an eye on him until he rounded the corner;-)
I've been wearing CK One for years, it just suits me. Although I would love to find the perfect "ocean" perfume, one that actually has that breezy slightly salty quality - without the synthetic notes.
On another note: I'm also still constantly amazed at how direct a smell can be, sometimes even evoking memories and moments you thought were long lost. Quite powerful.
