The Kardashian-Jenner Christmas Eve bash was filled with extravagant mommy-and-me moments.
She posted a photo of herself wearing a black lace and champagne Mugler dress with the comment "naughty or nice?"
Dark red lips and an Old Hollywood-style hairstyle were the perfect complements to the high-slit dress.
Even though the position clearly conveys naughtiness, we're choosing to go with nice based on the endearing Instagram Stories video Kylie uploaded with 4-year-old Stormi Webster.
Her kid performs a pirouette in an identical Mugler dress in the mirror selfie video.
In Stormi's case, the princess-style dress had lace that created an asymmetrical, one-shoulder appearance.
The young girl had a top bun on her hair and was beaming while wearing her gown.
Along with their 10-month-old boy, Wolf Webster, who was previously known as Stormi, Kylie Jenner and Travis Scott are parents to both of these children.
She donned a white silk robe on top of her sheer black catsuit because she wasn't wearing a bra underneath it.
