She even brought back the iconic bunny costume from "Legally Blonde."

Reese Witherspoon is in the mood for Halloween and is sharing some of her best costumes from years past.

The actress and entrepreneur posted a series of photos on Instagram, one of which included her unforgettable pink bunny costume from "Legally Blonde."

She also shared throwback snaps of her as a banana split, a zombie and a bear-like look as she held a large pack of Reese's peanut butter cups.

Witherspoon's Halloween-themed post has received more than 930,000 likes along with loads of comments.

Actress Ali Wentworth said, "I need that costume for a date night!" While actress and comedian Mindy Kaling chimed in saying, "Go off, spoon!"

Witherspoon celebrated 20 years of "Legally Blonde" in July by posting a series of photos of her character Elle Woods as well as behind-the-scenes clips.

"Time flies when you're busy using legal jargon in your every day life," Witherspoon captioned the post.

She continued, "But truly... playing Elle Woods was the role of a life time and I'm so honored to have been a part of sharing her story with you all. Every meme, graduation cap, musical number, halloween costume and bend & snap has brought me so much JOY over these past two decades! I wonder... what will Elle do next?"
