Julia Roberts and niece Emma Roberts match at NYFW

Two redheads, one very stylish family affair.

Julia Roberts and Emma Roberts stepped out at New York Fashion Week on Tuesday for their first joint red carpet appearance in 13 years.

The aunt-and-niece duo coordinated in head-to-toe black ensembles that emphasized their matching auburn hair.

Julia, 57, opted for a sharply tailored suit, pairing an oversized blazer and barrel-leg trousers with a crisp white shirt and striped tie. She accessorized with Jacquemus ankle boots ($1,190).

The look felt like a deliberate callback to the boxy Armani men’s suit and tie she famously wore to the 1990 Golden Globes, where she accepted her best supporting actress award for “Steel Magnolias.”

The Oscar winner has leaned heavily into suiting this year, most recently in a Versace navy blazer and striped shirt at the Venice Film Festival, a first look at the label’s new direction under creative director Dario Vitale.

She’s on the promotion trail for “After the Hunt,” a hotly anticipated psychological thriller by Luca Guadagnino, which she stars in alongside Ayo Edebiri and Andrew Garfield.

The actress also fronts the inaugural issue of 72 Magazine, the new venture by British Vogue alum Edward Enninful, which hits newsstands on Sept. 12.

Emma Roberts, 34, provided a feminine foil to her aunt’s more traditionally masculine tailoring in a floor-length black chiffon column dress with spaghetti straps and a draped back.

The “American Horror Story” actress wore her hair artfully mussed in a low ponytail and carried the Jacquemus small Ovalo bag ($890).

Off the carpet, she’s busy building Belletrist, the book club-turned-production venture she co-founded that has championed female authors and optioned literary works for the screen.

The Roberts women have more in common than their style chops. Both are working mothers: Julia shares three children with husband Danny Moder, while Emma welcomed her son, Rhodes, with actor Garrett Hedlund in 2020.

The family fashion moment was a rarity — the pair last walked a carpet together back in 2012 for the indie film “Jesus Henry Christ.”

On Monday night, they proved it was worth the wait, sharing cheek-kiss greetings and laughing with designer Simon Porte Jacquemus at the launch of his champagne with Veuve Clicquot in Central Park.
