Glamour with a goal! Amidst the red carpet fanfare of the 87th Annual Academy Awards, Reese Witherspoon pushed a campaign for gender equality. 

The Wild star, 38, took the time during the Oscars pre-show to promote #AskHerMore, a trending topic on Twitter that encourages red carpet reporters to ask leading ladies about more than just their style choices. 

"This is a movement to say we're more than just our dresses," Witherspoon explained to ABC ahead of the 2015 Oscars. "It's great the dresses are beautiful — we love the artists that make all these clothes -- but, you know."

"This is a group of women — 44 nominees — and we are so happy to be here and talk about the work we've done," she added. "It's exciting for me to get to talk to other nominees to talk to other women about the work they've done."

Nominated for Best Actress at Hollywood's biggest night, Witherspoon touched on the #AskHerMore campaign earlier on Sunday, Feb. 22, publicizing information about the mission on her Instagram account. She shared a shot of various questions that could be asked over images of Oscar-nominated women. 

"This movement #AskHerMore..have you heard of it?" she captioned the photo. "It's meant to inspire reporters to ask creative questions on the red carpet. I love the Oscars AND fashion like many of you - & am excited to share #WhoAmIWearing later tonight… But I'd also love to answer some of these Qs... There are so many amazing, talented nominees this year..! Let's hear their stories! Spread the word. #AskHerMore #Oscars #Countdown"

While she chose to keep the attention away from her Oscars ensemble, Witherspoon stunned just the same. The actress, who has been celebrated for her portrayal of Cheryl Strayed in the big-screen adaptation of Wild, looked elegant in a black-and-white off-the-shoulder Tom Ford gown with Tiffany and Co. jewels.
