Don't be tardy for the party waist training session with your mama!

Brielle Biermann, 18, and mom Kim Zolciak-Biermann, 37, both Instagrammed selfies in their "conic shapers." In the pics (Kim went for the full-body snap while Brielle opted for the zoomed-in version of the same photo), the ladies put their hourglass figures on display in matching cinchers. The Don't Be Tardy star even noted playfully, "A family that #waisttrains together stays together."

Of course, waist training isn't for everyone in the Biermann bunch (including Kim's athlete hubby Kroy Biermann or her five younger kids). There are some potential health risks involved, so it's best to wear those corsets with caution (if at all).

That said, after Kim had a Transient Ischemic Attack (or "mini stroke") back in September 2015, she reassured fans her health scare was not a result of her use of waist trainers. "By no means did my waist trainer cause my blood clot or my TIA. I would never use anything nor promote anything that I personally didn't love or something that was dangerous," she wrote in an Instagram post. "I LOVE LIFE WAY TOO MUCH! and I have a whole lotta living to do."

Lately that's included lots of family time, standing up to trolls online, and yes, posting a few coordinating bikini selfies with Brielle.

The apple doesn't fall far from the tree.
