Well, it's not often I fly to California only to play with French beauty products. But the Carmel Drug Store, established in 1910, carries a wide array of old-timey items that I just could not resist. (Carmel is a tiny, cute seaside town.)
If you don't wear perfume, a few dabs of Roger & Gallet Bois D'Orange fragrance water is a perfect stepping stone. It's a light-as-air citrus scent, and you can spritz it on in the morning or before a date.
Buy it: Carmel Drug Store, 71 Ocean Avenue, Monterey California (831) 624-3819; Ansonia Pharmacy in New York.
