Ha-ha - I had a chance to see "typical american woman". :)))
But mosty I can only say something about the exterior and a little bit about the public behaviour.
And to be honest: there are strong differences in style for white/african-origin/hispanic-orgin women :)))
I would rather suppose that "self-sufficient / independent / responsible" are rather stereotypes based on media :)))

And by the way - you look like typical white american woman in terms of the exterior :)))
