While several A-listers attended the event, including Kim Kardashian and Adrienne Bailon, Rihanna was the most stunning in an exquisite Zac Posen Fall 2014 gown in a dramatic deep rose hue.

The off-shoulder number features bold shoulders, a short train, and a lovely pleated detail. The gown’s mermaid silhouette perfectly hugged Riri’s curves. This might be her most elegant look of the year!

The stunning Chopard tourmaline-and-diamond necklace elevated the pop singer’s look, perfectly complementing her glamorous ensemble.

Rihanna enhanced the elegance with matching rings and a detailed ruby cuff adorning her tattooed wrist.
