I've just been given a (really) late birthday gift of Terre D'Hermes and although it's something I always wanted to buy myself, I was wary about doing so and adding another scent to a collection, half of which I don't even use. I now have 10 bottles by different houses. So it's a simple question. How many scents/fragrances do you use/own? Or are you a one signature scent man/woman/thing?
