Even more than music, scent will bring back memories. L'air du Temps (Lily of the Valley scent - I may have misspelled it) takes me right back to high school. My best friend and I felt like Audrey Hepburn when we wore it - utterly sophisticated. Jean Nate (lemon scent) My first business mentor out of college must have bathed in Jean Nate instead of water. Every time I sniff it, I am right back in her office. Happy memories - she was so good to me. When I travel I try to buy a bottle of something special. "Lily" by Santa Maria Novella takes me right back to Florence. What perfumes work memory magic for you?
