Ralph & Russo created the couture pieces just for the mother-daughter duo. Kylie's creation was a jaw-dropping, off-the-shoulder silouhette complete with a long bow at the hip and a thigh-high slit. She paired the glam gown with a massive emerald-and-diamond necklace, plus silky heels and glittery nails that matched the dress' green hue.
Little Stormi was grinning widely while holding her mom's hand in the pic. The tot's dress had puffy sleeves and a twirly skirt, and she accessorized with very sensible white sneakers.
Both dresses included personalized tags on the insides, with Kylie's reading "Mademoiselle Kylie - Haute Couture 2019," and Stormi's saying the same but with her own name embroidered on hers.
"Most wonderful time of the year ✨," the Keeping Up With the Kardashians star wrote on Instagram. "Thank you @ralphandrusso for the custom dresses."
