Way before Brandi Glanville appeared on The Real Housewives of Beverly Hills, she worked as a high-fashion runway and print model for 17 years — and that includes posing for the likes of fashion houses like Chanel, Giorgio Armani, and Gucci. You can take the girl off the runway, but she's still a model at heart: Brandi just shot a fun photoshoot at her house for Instagram, modeling a very sultry black one-piece swimsuit.

The Real Housewives of Beverly Hills alum and recent Celebrity Big Brother contestant worked her angles in an Instagram video she posted yesterday, writing: "Hair/MakeUp/Photog/ styling courtesy my Bestie @proudmia Attitude all Me Location:Home."

Hair up, or hair down? Brandi tried it both ways.

Loving this one-piece, with its studded belt detail! Brandi's not the only Housewife alum wearing a chic little black tank suit: Alexis Bellino from The Real Housewives of Orange County just made the case last week for a black belted swimsuit too!
