The 'Mad Men' actress showed off her fantastic figure in her latest Instagram update.

On Monday, July 13, Emmy nominated actress January Jones started off the workweek by uploading a stunning snap for her 1 million Instagram followers to enjoy.

The Mad Men star appeared to have taken the picture herself. She sat next to a pool on a sunny day, bathed in golden light, at an undisclosed location. Outdoor furniture and gorgeous green foliage can be seen in the background. The 42-year-old tilted her head and looked toward the camera, with a small smile playing on her lips.

She sizzled in a sparkling multicolored bikini top that left little to the imagination. The plunging garment showcased her incredible curves. Fans were also able to get a good view of her toned midsection. January piled on the accessories, wearing a glittery headband, coordinating sunglasses, and an intricate necklace adorned with numerous charms.

For the photo, the Spinning Out actress wore her short blond hair down in a deep middle part. She appeared to be wearing a minimal amount of makeup, allowing her natural beauty to shine. The cosmetic application seemed to have featured foundation, highlighter, and bold red lipstick.

In the caption, January made reference to a “heat dome” and implored her followers to research the term.
