Never one to shy away from posting revealing selfies, Kim Zolciak is kicking off 2015 by showing the results of her post-baby slim-down—and we have to say, the girl looks good!

On Tuesday, the Don't Be Tardy star took to social media to put on a mini fashion show, modeling two recent bathing suit purchases. "Trying on bikinis for my vaca with hubby," she wrote on Instagram.

Trying on bikinis for my vaca with hubby.. ??Thankful for @310nutrition for keeping me in check! The shakes really help me! You guys keep asking what's my favorite flavor, honestly I'm torn between vanilla and chocolate! I LOVE peanut butter so I add that to the chocolate one, and I love strawberries so I add that to the vanilla one! It's all depends on your preference. The cleanse is really helpful to jumpstart you! #NoFilter #HerveandAgent #ImPosingForYall #310shake #310Nutrition #MyHubbyLovesTheseCurves

Since giving birth to her twins in November 2013, Kim has happily showing of her svelte slim-down. In September, she took to social media to show off the results of a tummy tuck and boob job. Last July, the former Real Housewives of Atlanta star opened up about dropping the weight after welcoming Kaia and Kane into the world. "I gained 50 pounds [throughout the pregnancy] and nine days later, after I had delivered the babies, I lost 42 pounds," she shared last summer. "That's water and the babies," she added. "I had two sacks, two placentas, and two babies, so there was a lot."
