The article says that Gov. Palin did not request the digs, nor did she pick them out. I'm sure something like the following happened: She did not have the kind of clothes the party bosses thought would be apt for a national campaign. So, they bought them for her. They realized that she was attractive and wanted to make the most of that. I am no fashion critic, but I do not take her outfits to be elegant, vain, or immodest. They are classy.
None of this fits the category of John Edwards's draconian hair cuts. John Edwards is a prissy, vane elitist by nature; the haircuts confirm it. Gov. Palin is a popular and populist politician. Some high-end clothes will not change that. She hasn't started sounding like John Kerry or John Edwards or Hillary Clinton, has she--either in tone or in policy? You betcha, she hasn't!
Moreover, had she not worn these kinds of clothes, The New York Times and their ilk would have accused her of being a cultural barbarian out of step with national, political culture.
