Kylie Jenner and her 1-year-old daughter Stormi celebrated Christmas Eve in coordinating couture.

The youngest self-made billionaire and her little girl both wore custom Ralph & Russo emerald dresses, with Kylie strutting her stuff a sexy off-the-shoulder gown with a slit and Stormi looking festive in a short-sleeved dress made of the same material.

“Most wonderful time of the year ✨,” the 22-year-old makeup mogul captioned the pic. “Thank you @ralphandrusso for the custom dresses.”

The womenswear brand doesn’t sell children’s clothing off the rack.

Inside each gown was a custom tag with Stormi’s reading “Mademoiselle Stormi Haute Couture 2019” and Jenner’s reading “Mademoiselle Kylie Haute Couture 2019.”

The Kylie Cosmetics creator rocked matching green heels and a diamond and emerald necklace with her look. Of course, her manicure was also emerald green.

Stormi, going for comfort, wore white sneakers and white lacy socks with green bows.

The mother-daughter duo has been known to wear matching looks.

For Halloween, they twinned in butterfly costumes, and in January they wore mommy-and-me bathing suits.
