If you want to know where Gigi and Bella Hadid get their smart style sensibilities, you don't have to look further than their fashionable mom, Yolanda Hadid.

The Real Housewives of Beverly Hills star stepped out at the Global Lyme Alliance Gala in N.Y.C. on Wednesday night to help raise awareness for Lyme disease, and she could not have looked more elegant if she tried. Hadid wore a black lace Pamella Roland gown with an intricate neckline and a high leg slit. Her hair was pulled back, and she paired her outfit with simple hoops.

The mother-of-three has been open about her struggle with Lyme disease, which Bella and her son Anwar also have.

“I write in the book [Believe Me: My Battle with the Invisible Disability of Lyme Disease] when I was naked in the ocean and just feeling so sick and at the end of my rope that I was just trying to be one with the universe,” she told InStyle exclusively last month.

“It was like, Okay just take me, I cannot live one more day with this pain.”

We're happy to see Yolanda on the go and thriving.
