There you go again putting yourself down.
STOP IT!
I use Talia Shire as an archetype/sexy stereotype that it sounds like you could model yourself off of.
Given that we have 6 billion plus humans on this planet, we are bound to run into more than a few who happen to look alike.
Good examples would be:
"tatooed girl with dark hair". Go on suicidegirls.com for long enough and the girls will start to look all the same.
"Ditzy Blonde" would be Reese Witherspoon, britney spears, hilary duff, young cameron diaz
"brunette bad girl" would be eliza dushku
"girl next door" would be Kristen Stewart, Talia Shire,
"hot librarian" would be talia shire again
"schoolgirl" would be a young britney spears
"sexy asian chick"
Hollywood and media play on our base impulses so the actresses who make it would be those who can fulfill certain fantasies or be the projection board for those fantasies
Okay, I'll stop putting myself down. Just being factual though really.
Kristen Stewart wakes up and styles herself in no way (except on the red carpet) and looks hot because she's Kristen Stewart and she's hot.
I can't be anything but me. Styling or no styling. Thank you for the suggestions though, it's very interesting hearing this viewpoint.
