I have her book
Burlesque and the Art of the Teese. It's mostly a picture book, but she does talk a bit about her childhood and how she got in to make-up, style, stripping, and eventually burlesque.
She shared an anecdote in it, where she went on a cruise with her family when she was around 10-12 (I don't have the book here, so I can't fact-check right now). Some older ladies that they had met mentioned when they thought she wasn't listening that her sisters were very beautiful, and it was "a shame about the other one" (Dita). So, she figured that if she wasn't born with it, she could manufacture it.
I always loved that story, because I really do think most people are (genetically) capable of being attractive, if they care for their body and their skin, learn how to do their make-up and hair in a way that suits them, and learns how to dress for their bodies, while obviously also practicing dicipline in their eating habits. If you in addition to that learn graceful movement, almost anybody can become something special.
Most people just aren't willing to put in the effort.
