The dress is fine. The bulk of the lace doesn't suit her bone structure and frankly she looks far more comfortable in the tiny minidress she wore for the evening do, but it's fine. I find it a bit weird that the Hiltons, as wealthy as they are, went for the Orangery as opposed to a truly exclusive venue.
However.. all 3 of the Hilton ladies are hitting the plastic surgery hard. Nicky is the only one that doesn't appear to have any obvious fillers yet but she seems to have had some smoothing work. Paris' face looks very puffy.
