That's unfortunate that someone so insignificant would ruin your like of a specific perfume. Though I have to admit, sometimes I buy 'plain Jane' perfume with a giggle when I imagine Anna not wearing them just because they smell amazing on me and I get complimented and she despises them because they are accessible. Don't worry, nobody smells exactly the same wearing exactly the same perfume. That's the beauty of it! Anna would smell like Portrait of the Rat, complimented by the strong scent of tobacco she cannot quit consuming. With age, however, everyone will start smelling different as well.
P.S. Lauren, if you read this if Anna asks you what perfume is this, tell her any basic Betty's brand like Coco Mademoiselle, Mugler Angel, Dior J'Adore. The rat's nose, after munching on so many cigarettes, by now could not tell the difference.
