It usually doesn't happen since I test scents before I go out into the world. I've only gotten one negative comment, but only that he didn't like it as much. I sat next to this guy for 3 years. One day, wearing Bond's So New York, he said that it wasn't as nice as my other perfumes. I wear perfume lightly, for myself. I never knew he noticed. He went on to say, it was nice sitting next to me, because I didnt over do it, but that one wasn't as nice. So New York is strong and doesn't evolve. All my other scents change over time.
