The very heavily pregnant Kourtney Kardashian is still out and about less than two weeks before her third child is due. With her now enormous baby bump, Kourtney isn't sporting any maternity clothes but instead, she's hijacking her sister's closets and taking inspiration from their looks to come up with her own pregnancy style.

Last week, Kourtney took advantage of her youngest sister Kylie's closet and stepped out in clothes that she raided from baby sis. She posted a photo of herself wearing a white dress with a colourful Aztec print in front. She paired the loose-fitting dress with a tan cowboy hat and ankle boots which she wore for a day out with baby daddy Scott Disick. She revealed her little closet hijack job with the caption: "Shout out to my fashionista sister @kyliejenner for letting me borrow your dress AKA I stole it and you had no idea but for not freaking out when you see me wearing it."

Shortly after showing off her borrowed dress on Instagram, she posted yet another photo of herself and dropped a clue which could indicate that she's wearing even more of Kylie's clothes. In the photo, Kourtney was wearing a loose red flannel shirt over a tight fitting black dress. She completed the look with a black hat and dark sunglasses. She teased her sister with the caption: "Do you like my shirt @kyliejenner ?"

The red flannel shirt may be Kylie's but she's not the only member of the Kardashian-Jenner clan to rock the look. Just a few days before Kourtney posted her photo wearing the red flannel buttoned down shirt, Khloe also posted a photo of herself wearing similar threads.

Not to be left out, Kim Kardashian West and her hubby Kanye have also both been seen wearing a similar shirt in the past month. Kim posted a photo of Kanye in the coveted piece of clothing on September 22 with the rave: "I'm so lucky #MyFineAssHusband"

Kim was later seen wearing a red flannel shirt of her own just a few days after admiring Kanye's look. She stepped out in the shirt for a day out in Paris while she was there with Kanye, North as well as her mom Kris Jenner and her sister Kendall who walked several runway shows.

Kourtney is due to give birth near Thanksgiving weekend at the end of November. She is reportedly expecting a girl. Kourtney and Scott are already parents to four year old Mason and two year old Penelope.
