Both work for me.
I love the flirty skirt under the covered up top (Balmain) and pale pink pumps she wore at Letterman. And surprisingly I also love the denim Givenchy dress she wore last night. It’s so well done with the leather trim adding just the right amount of high end detail. They’d have to be careful who to put in this look though. I mean, on Britney Spears it’s a whole other story.
