I used to wear perfume every day: Jo Malone, Coco Chanel were amongst my favourites. Since I moved to Nova Scotia Canada, I have stopped wearing it, as all public places are perfume free zones. I couldn't believe it at first. Why? Well, it seems that many people have allergic reactions to the smell of perfume, and therefore it is generally discouraged.
Oddly enough, when someone is wearing it, I notice it much more now, and don't always enjoy the smell, especially men's cologne.
When I was in an airport lounge a couple of years ago, a woman sat next to me wearing a large dousing of Angel, which made me feel quite sick. The whole area smelled so strong, it was like a form of air pollution. Luckily she didn't sit next to me on the plane, as it would have been a miserable flight.
Funny that.
