Do you have a signature scent?

Apparently, it's National Fragrance Day. (It's also First Round of the NCAA Tournament Day, too, but I'm too nervous to talk about that.) I don't have a signature scent and I wonder if that's a bad thing. I was wearing Origins Ginger Essence for a long time. Then, I switched to Blue by Ralph Lauren. These days, I tend not to wear anything at all, unless it's a very special occasion. I think, where fragrance is concerned, it's hard to get it right.  Less is more. Still, I remember how my mother nailed it by wearing just the right amount of Chanel No. 5 (naturally) and I wonder if I should put more effort into the whole olfactory thing. Taking suggestions.... what do you wear, if anything?
