Ciara was a style stunner in her designer dress that featured ombre detailing from her black halter top to the purple hues on her hemline.

The star went braless for her backless ensemble which draped from her high neckline. 

The chart-topping singer highlighted her slim torso with a mauve leather belt which matched the color of Russell's suit and trousers.

She slicked back her long tresses in a low ponytail and kept her makeup in natural tones for an overall flawless complexion.

Get a sexy ombre look like Ciara

Ciara works the red carpet like she does the stage in an Elie Saab gown that shows off her well toned arms and legs. It's elegant and gothic but the sky high slit in the front give this an injection of sexiness. The belt gives this a tough edge.

Elie Saab is known for his intricate and luxurious designs. He's dresses have been all over the red carpet for Oscars and have been worn by everyone from Hally Berry to Jennifer Lopez.

We love how romantic this look is. Head over to Luisaviaroma to check out a similar version in black and white. Furthermore not all of us have an excuse to wear a ballgown, so we found cocktail length dresses that have this gothic glamour about them. These dresses would all be perfect on a first date or a night out with the girls. It's about balancing feminine details with showing just enough skin to be sexy. We would style these dresses with sky high strappy stilettos to really show off your legs.
