I think none at all. Humans are very sensitive to smell, and what scent appeals to one, will no doubt disgust another.
Not to mention those of us who get headaches, sniffles and watery eyes from perfumes. I cannot walk through department stores, due to the bombardment of different smells.
Nothing smells better then a fresh, clean person. Plus, with all the fragrances that go into laundry detergent, shampoo, soap, deodorant and make up, why do we feel the need to spray on some more? I don't want to smell like a bouquet.
