Are you a signature perfume sort of girl or do you have a wardrobe of fragrances for different occasions?

I've been looking for a new perfume for months now and it is'nt easy! There are so many different ones to consider and what they smell like on the testing paper can be very different to what they smell like on your skin. Of course there are only so many you can spray on yourself on one visit to the store without getting totally confused! I like having a signature perfume but when your old favourite gets discontinued or impossible to get (I am very wary of buying fragrance online) then you have to start again.

What draws you to try out a new fragrance? If you like a designer do you try their perfume or do you prefer a scent from a true cosmetics house? Do you prefer a heavier or light scent? Do you take into account your partners opinion or do you just wear what you like?
