Cut is great, colors are playing together a bit too rudely for my taste, but: WHY can I see so much of the outline of her boobs? It's almost intimate. It's sternum shading. It's pushing them down and then outlining them. It's SUPER distracting, and now that I've noticed it, it's all I can see. Because the dress is Prada, I'm starting to think -- between this and the Hathaway Non-Nipplegate Controversy from the Oscars -- that Prada fired everyone and hired some thirteen-year old boys.
This is cuter, at least. If you're going to look at her breasts, it might as well be for interesting reasons and not brain-melting ones.
This is great on her, though -- ladylike, colorful, well-shod. I wish there was an evening gown version of this she could've worn instead. Snap your fingers and make it happen, Dockery. Everyone's worried about Lady Mary because of the SPOILER, Can't you play on their guilt?
