That's actually a cute dress. She should wear a very slim mid thigh slip underneath (heck a spanx would do). When I saw the dress incident first, I thought that she had been very lucky, because the dress while flying up, didn't really end up over her head, and looking at the pictures it is almost incredible that it didn't do just that.
Def. a more luck then hair moment... ( I know it is more hair than wit, but seriously we never doubted that, have we?)
I also wish she'd leave her hair this length. It is immeasurably better.
