Nicole looked stunning in a daring black lace halter top with a floral pattern, which highlighted the star's trim frame.
She coupled the look with a pair of high-waisted, wide-leg orange trousers and sky-high strappy black heels.
Nicole kept her look simple for the occasion, accessorizing only with a gold arm band, and carrying a black leather clutch.
