The Fifty Shades of Grey actress, 25, went retro in a strapless, tea-length black cocktail dress, compliments of Christian Dior, which she teamed with matching strappy sandals and a small clutch, both by Roger Vivier. A diamond strand necklace and stud earrings by Bulgari completed the elegant ensemble.

But she wasn’t the only stunner at the event! Johnson was joined by Ciara, who donned a jade-green tank, a leather skirt, and a ruffled train, all by Roberto Cavalli. She accessorized the look with Giuseppe Zanotti sandals and some arm candy—the handsome Peter Dundas, the designer behind her getup.

And then there was Alessandra Ambrosio, who kept things short and sexy in a heavily embellished, lime-hued Dsquared2 mini, teamed with Bulgari baubles, a box clutch by Elena Ghisellini, and metallic gladiator heels.

Of course, the prettiness continued inside the event, too. During the dinner—the seventh annual event in the city, which raises funds for AIDS research—Heidi Klum (in peekaboo Atelier Versace and Lorraine Schwartz jewelry) and Michelle Rodriguez cozied up to Kenneth Cole for a group shot.
