Celebrating the grand opening of the extravagant JW Marriott Chicago earlier this month, Emmy Rossum stepped out in a stunning mustard yellow Amanda Wakeley dress with Rene Caovilla shoes before giving a live performance of "Think of Me" from The Phantom of the Opera.

The British label silk satin dress with plunging v-neckline and elegant side overlay skirt draped beautifully on her figure. The actress accessorized her standout dress with a simple thin leather belt, dazzling earrings and a classic gold clutch. Warm neutral makeup shades and a soft, romantic updo completed her look.
