The look was giving mid-2000s.

Reese Witherspoon may not be a Millennial, but she definitely harnessed some of the generation's style energy with her latest look.

The actress hit the red carpet of the Your Place or Mine movie premiere on Feb. 2, at Regency Village Theatre in Los Angeles, in a mid-2000s-reminiscent outfit, smiling and posing for photos at the event.

Colored in a bright, turquoise blue hue, the girly midi dress featured a strapless structured bodice and a peplum silhouette. She accessorized with simple black Aquazzura heeled sandals and minimal David Webb jewelry, opting for neutral makeup with a side-parted hairstyle worn down in loose waves.

The 46-year-old took to social media, uploading an Instagram Reel showcasing a behind-the-scenes preview of her getting ready pre-event. Set to the tune of a sped-up remix of Miguel's "Sure Thing," the camera panned over a few clutch and shoe options, before zooming in on the chosen dress she would wear for the occasion.

Witherspoon then emerged from her dressing space, opening a set of wooden double doors as she walked out, flashing a grin at the camera and pushing her hair behind her ear as she showed off the finished ensemble.

"Getting rom-com premiere ready ✨💫" she wrote in the caption.
