Kourtney Kardashian‘s pancake breakfast baby shower really took “dress code: casual” to new heights.

On Sunday, Kardashian’s girlfriends threw the pregnant reality star an informal shower at IHOP, with everyone in pajamas.

Kardashian, who’s expecting her third child with boyfriend, Scott Disick, sported red loungewear and a matching fuzzy devil horns tiara.

“I have the best friends in the world! Sunday morning 9am IHOP in our pajamas! #fancyBabyShower,” she posted on Instagram, along with a group shot of her pj-clad gal pals.

Every party needs a signature drink, and Kardashian’s was likely the perfect sip for a pregnant guest of honor — a mug of hot chocolate topped with hefty helping whipped cream. Clearly, she and her niece have similar tastes in beverages!

After indulging in IHOP’s breakfast bounty, the partygoers ended the shindig with a sweet finish: a white basket-weave cake with a “Happy Baby Shower Kourtney” sign.

It was the second baby shower in a week for the expectant star. Five days earlier, her sisters Kim Kardashian, Khloé Kardashian and Kylie Jenner threw her a brunch with a Breakfast at Tiffany’s theme at the Conservatory at the Montage in Beverly Hills.

For that party, we’re guessing that pajamas were optional.
