I'm a jewelry designer (who has designed for private label) and my own line, and I can't imagine suddenly becoming a chemist overnight, setting up a lab so I can design a fragrance. Even clothing designers when they put out a jewelry line, don't design it. They outsource to companies with designers, and those designers pitch a few sample lines that think would be appropriate. And the way that usually works is that they'll say design me something kind of like so and so's line, but at this pricepoint and tweak this part with fill in the blank.
