This seems very elegant and appropriate for a party thrown by the United Nations.

With the fashionable bits of interest not forgotten, but well and smartly confined to accessories. I am really into this tiny little bag, even if I could not fit anything I need into it.
I LOVE this coat/dress/coatdress. (I think it's a coatdress, as I saw photos of her wearing this inside the United Nations) and I also covet the bag. I don't always love with Emma Watson wears, but she is so good at looking interesting and elegant at the same time. It's a real skill.
