That '70s bump! Pregnant Chrissy Teigen and Kim Kardashian attended the CFDA/Vogue Fashion Fund show on Tuesday, Oct. 20 in L.A. and both of them had the same fashion inspiration: the 1970s.

Teigen went full-blown flare in burnt-orange suede bell bottoms, which she accessorized with a black leather sash. The model, who announced she was pregnant Oct. 12, paired the pants with a silk burgundy top featuring an off-the-shoulder cut that emphasized the Jane Fonda-era vibe. The mom-to-be posed with her hubby, John Legend, who wore a blue suit with a crisp, white shirt and brown shoes.

Kardashian, who is expecting her second child in December, donned a more subtle nod to the time period with a navy blue bodysuit, geometric gold Altuzarra skirt (with a thigh-high slit).  A draped navy duster completed the dressy ensemble. Even more '70s were her golden strappy heels with chain details, perfect for her retro aesthetic. 

The mom of North West, 2, attended with her husband, Kanye West — who sported a white button-down shirt with light-wash denim for the occasion. After the couple arrived, Anna Wintour gave West a quick kiss on his cheek before leading them to their seats, an insider told Us Weekly. The pair sat front row, next to the Vogue editor-in-chief as they took in the industry-sponsored event. 

Later that evening with a full outfit change and clad in all black,  the fashionable couple attended the CFDA/Vogue Fashion Fund dinner sponsored by Perrier-Jouet at Bouchon Bistro in Beverly Hills.
