seems like she was at a loss once she was out of her familiar environment. i can see how that can happen to anybody, Vogue editor or no. i often think of style as camouflage, to help you blend into your environment.
I think being a Vogue editor made her even more a person of her environment. Where personal style is trend-driven, not personal.
I really liked her second point of being in her 30s and not finding clear direction. considering the several threads i've encountered on how to dress in your 30s, or what length skirt is appropriate at x age, i think that's something that many of us could relate to. i thought she had a good point.
