January Jones‘ swimsuit moment is the pinnacle of vintage summer chic!

Earlier this week, the Mad Men alum shared a truly jaw-dropping photo of herself living her best life in the heat wave. She shared the photo with the caption reading, “Only cause it’s a heat wave..”

In the stunning photo, we see Jones channeling her inner pin-up in this stunning swimsuit. We see her smiling from ear to ear as she poses in a bikini comprised of a red and white checkered top and high-waisted polka-dotted bottoms. Not only is it 50s-inspired, but it’s so dang chic, and it reminds everyone she’s a confident goddess!

(These happen to be the Celine pointed white sunglasses, the JUILLET Tutti Top in Primrose, and Luisa Bottoms in Polka Dot, if you wanted to know the details!)

In a previous interview with Shape, Jones talked about her self-care and fitness routines, saying how she’s embracing her body in every stage it’s been through so far.

“After I had my son, Xander, I wanted to feel strong because my body had changed so much,” she said. “As he got bigger and I was hauling around a 20- or 30-pound toddler, my lower back gave out and I saw my shoulders starting to curl and hunch… I’ve gained weight because I’ve put on muscle. I’ve gone up a size in clothes, but I feel like I look better naked.”
