What do Blue Ivy Carter, Apple Martin and Kaia Gerber have in common (besides famous parents, that is)? A fondness for Reformation’s bestselling dresses.

A longtime favorite of A-listers like Taylor Swift and Jennifer Lopez, the sustainable LA-based label has also become a hit with Hollywood’s next generation, with Beyoncé and Jay-Z’s fashionable firstborn stepping out in its styles twice in the past month alone.

First, 11-year-old Blue Ivy attended grandmother Gloria Carter’s wedding in early July wearing the draped Bryn Silk Dress ($328) in a soft shade of artichoke green.

And just a couple weeks later, she styled the off-the-shoulder Filis Denim Minidress ($178) with Fendi shades and a gold nameplate necklace for the opening of Jay-Z’s “The Book of Hov” exhibit at the Brooklyn Public Library.

But Queen Bey’s No. 1 backup dancer is far from alone in her love for Ref.

In late June, Adam Sandler’s daughter Sunny, 14, joined her parents at the red carpet premiere of Netflix’s “The Out-Laws” in the brand’s Frankie Silk Dress ($298).

Reformation also popped up at the Paris premiere of “Oppenheimer,” with Matt Damon’s 24-year-old stepdaughter, Alexia Barroso, sporting the ultra-popular Nikita Dress in black — which, while no longer sold, is available at Rent the Runway for your next red-carpet outing.

Below, shop Ref looks spotted on (and inspired by) the most stylish celebrity spawn. We can’t all have superstar DNA running through our veins, but with looks starting at under $50, it’s never been easier to look like you do.
