Renee also donned a Vera design which she teamed with gold jewelry and Jimmy Choo shoes.
Also at the event were Nicky Hilton and Mila Kunis.
Nicky was super pretty in a color-complimenting shade of pink dress teamed with nude Louboutin peep-toes. And Mila was another star in a Vera Wang design and - like Reese and Renee - also opted for strapless.
Some black leather wrap-up sandals - also from Vera Wang - completed her look.
