A perfumer is someone who designs scent. The best perfumers can design individual, custom scents for their clients, attuned to body chemistry, wand length and wood, magic aptitudes, colouring, weight, personal preference and many other factors.

I've been getting mine formulated for me at Ardenia's since I began modelling, or nearly. I plan to take you when you get a little older, too. Of course, until you're fully grown you will have to have it adjusted periodically. And one's combination changes with pregnancy as well, but generally not too drastically.
