North West matches her blue hair to her denim set in Rome with Kim Kardashian

Blue is her color.

For an afternoon out and about in Rome, North West, 12, once again stole the show with her all-blue outfit.

Joined by mom Kim Kardashian, the tween sported wavy, waist-length hair, done up in two long pigtails, that perfectly complemented her denim-on-denim look.

West was clad in a light-wash jean jacket with two front pockets and a matching pleated miniskirt.

Her footwear moment was equally as statement-making, opting for a pair of chunky white high-top Isabel Marant sneakers with a hidden heel ($790) and frilly polka dot socks.

She sprinkled in high-end designer accents into the look, including a sparkly silver Balenciaga purse ($6,850) and a crystal-encrusted Vivenne Westwood Orb necklace ($595). 

The 12-year-old added some extra coverage to the leg-baring bottoms, layering a pair of black tights. She finished the bold street style getup with clear square-shaped glasses.

Kardashian, on the other hand, went with an all-black ensemble include of a crop top with a plunging neckline and a matching maxi skirt featuring a high slit.

The Skims founder accessorized the set with a long cross pendant necklace, black strappy heels and a black Hermès Birkin bag.

Over the weekend, the famous mother-daughter duo were spotted heading to dinner at Pierluigi, with Kardashian in a sultry black slip dress and her eldest daughter in a black corset with a ruffled lace-trimmed miniskirt and five-inch boots.

Some questioned Kardashian for the tween’s look. “pls can ppl stop dressing their CHILDREN like adults tf like north west is literally 12 YEARS OLD in a corset and a mini skirt?!?!” one X user wrote.

Meanwhile, a second added, “North west could have def put a cute little collared shirt under that GROWN ASS corset. Then it would have been more appropriate.”

We’re curious what North will model next.
