Jenna Dewan-Tatum brought a pop of colour to the Buick '24 Hours of Happiness' test drive launch event, held at the Ace Museum in Los Angeles, California.

The beautiful brunette sizzled in her sleek style, a fusion of contemporary fashion with seduction and femininity, in her tangerine Solace London Spring 2015 dress.

Jenna flaunted cleavage as the dress featured a plunging neckline along with cut-outs, and was styled with embellished white sandals.

She also added a bold cherry lip colour to her ensemble, and was certainly the belle of the ball.
