North West joined Kim Kardashian at Paris Fashion Week on Tuesday, wearing a vintage varsity jacket from father Kanye’s defunct aughts-era streetwear business, Pastelle.

Founded in 2004, Pastelle was West’s first genuine fashion endeavor — yet despite creative involvement from industry luminaries like Dior Homme’s Kim Jones and the late Virgil Abloh, the collection never made it to shop shelves.

The “Heartless” rapper, 45, famously donned North’s red-and-blue look at the 2008 American Music Awards, and it’s since become a collector’s item; one even went for $10,000 on the secondary market earlier this year.

North appropriately chose the jacket for the Dior Homme menswear show, pairing it with a mini Balenciaga bag ($1,950) and the brand’s platform Crocs ($950).

Mom Kardashian, 41, also wore Balenciaga for the occasion, sporting a camo top and neon green “pantyhose.”

Family ties aside, it’s not surprising North would pull out such a rare piece in Paris. Her extensive handbag collection includes styles from Louis Vuitton, Fendi, Dior, and Judith Leiber, and she’s been known to borrow Kardashian’s designer heels.

The tiny style star, who landed her first fashion campaign when she was just 5 years old, recently celebrated her 9th birthday by whisking her pals off to “Camp North” aboard Kardashian’s private jet
