Beyoncé and daughter Blue Ivy share this under-$200 ‘It’ bag

For Beyoncé and Blue Ivy, fashion is a family affair.

The 42-year-old pop star toted an asymmetrical Aupen Purpose Bag ($180) in an Instagram video on Sunday — just months after her 12-year-old daughter carried the exact same “It” bag at the “Renaissance” film premiere in London.

The “Halo” singer styled hers in keeping with her “Cowboy Carter” aesthetic, pairing it with a Prada Bolo Tie ($550), Fleur Du Mal Vegan Leather Shorts ($225), Saint Laurent boots and a Stetson cowboy hat.

Meanwhile, Blue Ivy put a dressy spin on the look for her red carpet appearance last fall, going glam in a silk Versace dress.

The tween’s emerged as a style star in her own right over the years, whether taking the stage at the Grammys, starring in Ivy Park campaigns or dancing up a storm during the “Renaissance” tour.

But you won’t need a famous mom like Béyonce to shop the buzzy bag, as it’s currently in stock on the Brooklyn-based brand’s website; a slightly larger version, the Purpose Deluxe ($260), is also available.

The Carters are hardly the only famous folks obsessed with the Purpose; the in-demand design has also appeared on the arms of Hailey Bieber, Selena Gomez, Tracee Ellis Ross, Lindsay Lohan and Olivia Rodrigo (to name but a few).

Meanwhile, Taylor Swift’s carried the brand’s currently-sold-out Nirvana bag everywhere from Jack Antonoff’s wedding to date night with Travis Kelce.

“Influenced by art and architecture, we wanted to move away from the idea of perfection and embrace irregularity and to truly appreciate beauty with all its flaws,” the Aupen team, who prefer to remain anonymous, previously told Page Six Style of the label’s signature asymmetrical shapes.
