January Jones has been flashing her undies on the red carpet and broadcasting the whole thing to Instagram. The 43-year-old Mad Men actress, who continues to make headlines for those bikini posts, went more covered-up in a recent social media share, but she kept it spicy via a dress with quite a slit.

January updated her Instagram ahead of the weekend, marking her attendance at the In Style awards and definitely going stylish. She even channeled the current '90s trend. Check it out below.

Scroll for the photos. January joins stars including The White Lotus face Alexandra Daddario in attending fall 2021 In Style events.

All smiles, January shared three shots of herself backed by a branded wall. The blonde had gone strapless in a satin and two-piece-effect dress, one that was pistachio green up top and black down below. The latter brought a slit skirt finish, with the very high thigh slit peeping the mom of one's black undies - white boots completed the unusual look.

January, who went with minimal makeup aside from her bold red lip, posed with her signature blonde hair down in a wavy bob, with a caption tagging her at Getty Museum. She told fans: "Fancy/foggy night out for @instylemagazine awards honoring such amazing people. Thank you @laurabrown99 for bringing the fun 💚."

Quick to leave a like was Legally Blonde actress Selma Blair, with fans throwing Jones over 26,000 likes. "Yes. Love this look," one user replied. Swipe for the gallery below, scroll for more.

On Her Fitness

The self-care queen, whose shelfies come with quite the $$$ on the skincare front, continues to make headlines for looking sensational at 43. Speaking of her X-Men training, Jones told Shape:

"It’s not that I wasn’t active. As kids, my two sisters were runners, I played tennis, and we all swam. But on a regular basis I wouldn’t work out, ever. Even when I was filming X-Men and they had trainers for all of us, I would lie and say I was exercising in my hotel room, when actually I was watching Friends and having full tea service.”

Celery Juice Secret

L.A. is L.A. Jones joins the smoothie-loving celebrities, and she even name-dropped her favorite diet secret as she detailed her nutrition and exercise.

“I don’t deprive myself of anything. If I want something—steak, a bagel—I’ll eat it," she continued, adding: "There’s no diet or strict set of rules. Last winter, I started drinking celery juice every day, and I’ve seen amazing results in my energy, digestion, and skin and how I sleep."

January has since updated in her adored matching sweats while tagging both singer Britney Spears and TV mogul Oprah.
