"You seem to saying style excludes having a personality." Not at all, but I doubt that the people I listed would have expressed personality through their clothes in the way you or I might. (might have had contractual or societal obligations etc)
Where does Chimamanda Ngozi Adichie sit? She's incredibly stylish. She is known for her talent but she is also stylish and beautiful.
I could have listed people like Michelle Obama, Iris Apfel, Grace Jones, Princess Anne, Judi Dench ....
My intention was to point out that some styles or fashions won't look good if that style doesn't suit your body.
I'm definitely not of the opinion that you need to be tall, thin, white and under 21 to look good.
