January Jones, 44, shows off her fit figure in a skin-tight bodysuit with a bikini design

January Jones flaunted her slim figure in three snaps she shared with her 1.1M Instagram followers on Sunday.

The 44-year-old beauty posed in the mirror wearing a long-sleeved, one-piece body suit dress that hugged her sensational figure.

The Mad Men star, who recently recovered from knee surgery earlier this year, captioned the post, ‘overdressed? or underdressed? for a Carnival themed holiday party. So fun @charlizeafrica CHARNIVAL.’

Slimming bikini illusion: January Jones, 44, flaunted her slim figure wearing a long-sleeved, one-piece body suit dress that hugged her sensational figure on Sunday

The mix of light and dark shades created the illusion she was wearing a bikini underneath a sheer coverall.

Yellow and blue circles printed on the fabric mixed with darker tones between her thighs creating the illusion of slimming leg outlines, but the dress was not see through at all. 

January rocked silver heels with the zip up stretchy bodysuit and slicked her hair back in ponytail styled with a part in the middle. 

She added a touch of blue smokey eye make up, bold red lipstick, and a little blush adorned the actress’s face allowing her fair porcelain skin to shine through.

The X-Men: First Class star sported circular hooped earrings and dark maroon nails. 

Since her 2020 Netflix show Spinning Out was canceled after one season, January has been spending more time with her 11-year-old son, Xander.

The actress has kept the identity of the biological father private, and raises her son on her own. 

During a past interview with Red Magazine, the talented beauty explained, ‘I just don’t feel I need a partner. Do I want one? Maybe. But I don’t feel unhappy or lonely. It would have to be someone so amazing that I would want to make room.’

A proud single mother: January recently shared an Instagram post earlier this month to her 1.1 million followers for a special tribute to her son, Xander, who just celebrated his birthday

She went country: She got trolled for this post where she posed in cut-offs shorts while modeling a trucker hat and holding a beer in front of a tractor. Some fans did not appear to appreciate her country look

She added, ‘Someone who would contribute to my happiness and not take away from it. I realize I have very high expectations and will probably have to compromise, but my life is so full.’

The star recently hit back at some ‘toxic’ troll comments she received on a post where she was wearing cut off shorts, a trucker hat and holding a beer in front of a tractor. Fans did not appear to appreciate her country look.

January responded by posting an image of herself in an all-pink bikini with the message: ‘⚠️ TOXIC FEMININITY⚠️ – Apparently you guys didn’t appreciate my attempted Nascar’esque rebranding so here ya go.’ 

Having fun: January Jones clapped back at critics who seemed to only want her to look hyper feminine and proper by sharing a photo of herself in a bikini top with high-waisted bikini bottoms

And they seemed to love her clapback. One fan applauded her for being such a ‘captivating comedienne.’ 

Other fans were so enamored by her photo that they gushed: ‘You are so beautiful’ 

Meanwhile, other fans were keen to encourage January’s quirky side and replied: ‘Your NASCAR-esque adventures are the best part. A-typical with a lot of personality.’
