Kyle Richards is feeling nostalgic!

The Real Housewives of Beverly Hills star took to Instagram on Monday to share a flashback photo of herself and sister Kim, proving that nothing can break the bonds of sisterhood — not even bangs.

“Omg this flashback of my sister @kimrichards11 and me,” she wrote. “Those bangs!!!! #why? #90’s.”

Kim responded with a picture of her own, depicting the two with no bangs and happy smiles.

“Sisters…look no more bangs!! @kylerichards18,” Kim wrote, adding “Although I loved our bangs back in the #90s #sisters #bangs.”

The two have been seen spending more time together as a family. Kyle shared a photo on Instagram in early August with her sister at a family baby shower held in honor of Kim’s eldest daughter Brooke Wiederhorn. Wiederhorn gave birth to a baby boy, Kim’s first grandchild, in October.

But this isn’t the first time that Kyle has posted a flashback from the 90s! She recently shared another throwback of longtime pal Bethenny Frankel in early November for The Real Housewives of New York City star’s birthday.

“Happy birthday @bethennyfrankel friends for more than 2 decades …love you XXOO 1992,” Richards wrote in the post of their big hair and classic ’90s style.
