Kim Zolciak-Biermann's Sexy Miami Style Includes a Long Jacket ... And No Shirt

Bethenny Frankel isn't the only one flashing some abs this week. Kim Zolciak-Biermann just posted a photo from Miami and it could be one of her most risque looks yet. (Watch the video above to see her style evolution throughout the years.) While Bethenny opted for a crop top, the Don't Be Tardy mom picked out a jacket — and that's it, with no shirt underneath. Leave it to Kim to make a long cardigan look this sexy. We're also impressed with how she tied this cardigan to prevent any possible wardrobe malfunctions. 

This outfit is definitely worthy of a fire emoji, but instead Kim added a couple heart eyes and wrote: "Miami nights!" Kim's Miami trip is definitely heating up.
