Well, Sarah didn’t always dress modestly. I can remember the crazed reaction at FR when a photo of her wearing a white jersey-like blouse was published. Some people here wanted to brand her with a scarlet “A”. I loved it! In the immortal words of Zero Mostel (or Mel Brooks): “If you got it, flaunt it, baby, flaunt it!”
I haven't seen the white blouse, and I loved her fashions during the 2008 election (I remember when the left lost their minds when $150K was spent to dress the middle-class Palin family, making it even harder to take the awful and extravagant get up of the linebacker Moochelle). Most of the outfits fit her very nicely, but I don't remember any that flashed skin.
