Kim Zolciak-Biermann Wore a Plunging Top and Cage Bra for a UFC Date Night

What does one wear to go watch a UFC fight for date night? If you're Kim Zolciak-Biermann, you go with something super sexy — and very, very Las Vegas. The Don't Be Tardy mom snapped a photo with husband Kroy Biermann while the two were out and about in Sin City, and Kim dressed the part with this glam, all-black outfit.

Kim went with mermaid-esque blonde waves, tight ankle-length leggings with heels, and a very plunging black top — accented with what looks like a cage bra. We don't know if this strappy bra is built in to Kim's shirt or if she layered it underneath. Either way, this top could draw some attention away from the ring! The whole outfit is smoking on Kim, who recently opened up about her breast reduction and the technique her surgeon used so she doesn't have any scars.

"UFC tonight in Vegas," she wrote in the caption. "Such an insane experience in person, my heart was pounding the whole time."
