Christie Brinkley and her daughter Sailor could have passed for twins in their latest social media post.

The 71-year-old supermodel and her 27-year-old lookalike child, also a model, coordinated in matching orange looks designed and styled by Donna Karan.

Sailor, whose father is Christie’s ex-husband Peter Cook, posted an Instagram reel detailing their outfits on Monday.

She captioned the post to her nearly 200,000 followers: ‘This morning getting styled by DK herself @donnakaranthewoman in @urbanzen benefitting @solvingkidscancer.’

The duo even mirrored each other with blond ringlets and natural-toned strappy sandals. 

‘This is for my TikTok,’ Sailor said to Donna before asking her to ‘explain the look.’

The veteran designer was similarly dressed in a draped red ensemble with long chains with statement pendants around her neck.

She added, ‘This is the best dress because you can do it six different ways,’ before demonstrating the piece’s variations.

The wrap dressed boasted a plunging neckline and was complemented by matching trousers, creating a monochrome effect.

The women sipped on summery cocktails at the swanky event, the Solving Kids Cancer Annual Hamptons Luncheon held at Tutto II Giorno.

Their outing comes after Christie recently revealed she was nearly brought to tears while recording the audiobook component of her memoir Uptown Girl, which was published in April.

Inside the pages of the literary work, she recounts her tumultuous childhood, four marriages, and multiple near-death experiences.

Christie told Social Life Magazine in July that sharing such personal anecdotes was profoundly moving.

‘There were parts where I thought, “Please don’t cry,”‘ the mother-of-three told the publication.

Among the most heart-wrenching stories told in her book was the tale of her painful divorce from Sailor’s dad Peter; pictured in 1999

Among the most heart-wrenching stories was the tale of her painful divorce from Sailor’s dad Peter. 

In her book, the actress recalled the shocking way she discovered the architect’s infidelity, which she confessed ‘nearly broke’ her.

She recalled that a man, whom she did not know, approached her to share the bombshell revelation right before she was set to deliver a commencement address at Southampton High School.

Christie described how the man softly told her: ‘Excuse me. I need to tell you that arrogant husband of yours has been having an affair with my teenage daughter.’

‘I knew from Peter’s face that he was guilty, and in that moment, I thought I was going to pass out onstage, in front of hundreds of people,’ she wrote. 

Their subsequent divorce led to a six-year court battle.

In addition to Sailor, the blond Hollywood vet is mom to daughter Alexa Ray, 39, whom she shares with ex-husband Billy Joel, and son Jack, 30, whom she welcomed with ex-husband Richard Taubman.
