January Jones is throwing it back to 2011.

The 43-year-old actress is among the stars preparing to celebrate the 78th Annual Golden Globe Awards and took to social media to show off her outfit.

On Sunday, Jones shared a side-by-side image of herself wearing the same stunning red Versace dress that she'd worn to the awards 10 years prior.

The brightly-colored, floor-length gown features a plunging neckline and cutouts across the torso.
