‘I LOVE seeing in my girls in my swimsuits! Funny story about this print! I fell in love immediately with the lime green and purple.. both my girls were like “Nah that’s a hard NO,”‘ Kim remembered in her caption.

She added: ‘Well the suits arrived and of course their “favorite suit ever” is this print Guess you guys loved it too because it SOLD OUT in minutes.’

Kim, who started the line last month, wrote: ‘We restocked and have only a couple sizes left. Make sure you join our email list so you are the first to know when we drop new suits, restock etc.’

Kim and her husband, former NFL player Kroy Biermann, share four biological children together – Kroy Jr., nine, Kash, seven, and twins Kaia and Kane, six.

Kroy also legally adopted Brielle, 23, and Ariana, 18, who are Kim’s daughters from previous relationships but have taken their stepfather’s last name.

The family now star on the reality show Don’t Be Tardy, which started off with the title Don’t Be Tardy For The Wedding while Kim and Kroy were engaged.

Although the new season was scheduled to premiere this summer it has been delayed, and this Monday Kim revealed on Twitter that it will bow in October. 

She revealed in Instagram comments that the show was to premiere in ‘July but because Bravo was unable to film this last few months  pushed to Oct’.
