Orange you sexy!

At the Hollywood Stand Up to Cancer event on Jan. 28, Reese Witherspoon worked an orange Roland Mouret dress with a plunging neckline. The cleavage-baring style is a refreshing change for the mom of three, 37, who usually opts for a more conservative cut. The coral dress also featured white side panels to highlight Witherspoon's tiny waist. She finished the look metallic heels and Irene Neuwirth jewels.

Witherspoon, who co-hosted the fundraiser with her husband of nearly three years, Jim Toth, kept her hair and makeup simple. She wore an orange-toned lip color and added a few waves to her bob for texture.

The "This Means War" star wasn't the only celeb who got glam for the event. Jessica Alba (showing off her new "fashion bob"), Anna Kendrick, and Gwyneth Paltrow, who flashed her toned abs, also attended the star-studded reception.

Witherspoon recently showed off her trim figure in a bikini while in Hawaii with Toth to celebrate Justin Bartha's wedding to trainer Lia Smith. The hot mama has said she relies on a sensible approach to maintaining her figure. "I work out all the time anyway just to stay healthy," she told Us Weekly in 2012. "I don't believe in crash dieting or anything like that."
