She's so thin right now. Her hips guarantee that she'll always be shapely and curvaceous no matter how much weight she loses tho. Tina blessed her in that department.
I don't mind the length of the outfit; I'm sure it's for her performance and the party was private. If it was a state event that may have been different. I hate that we probably won't get videos tho. I'm sure POTUS and FLOTUS had a ball.
Check CNN, the party invitation said to wear something appropriate for DANCING and DANCING shoes.
Lots of the male guests didn't even wear a tie.
Her dress and shoes are appropriate for the event especially since she was performing too.
