Who wore Cavalli better?

Nicky Hilton dropped by Hollywood nightclub Villa in this printed Roberto Cavalli dress and a pair of Christian Louboutin foxtrot platform slingbacks.

Jennifer Lopez then hid her pregnancy underneath the same silk Cavalli dress at the designer’s Just Cavalli NYC store opening.

I think JLo wore it better. Nicky looked so sullen in this photo and the dress seems to be wearing her not the other way around, get what I mean?
