When you're dating the son of one of the world's most respected and renowned fashion designers, you'd hope you'd be able to bag (or at least borrow) a few pieces from their runway collections.

And that's exactly what Chloë Grace Moretz appears to have done, if her latest wardrobe choices at the Sundance Film Festival on Sunday are anything to go by.

For the film festival, the actress wore not one but two outfits designed by her boyfriend Brooklyn's mother, Victoria Beckham.

The pieces perfectly oozed the star's laid-back vibe, with expert tailoring and a minimalistic tonal base that screamed the 'Beckham' aesthetic.

At a talk about her movie The Miseducation of Cameron Post and the Outfest Queer Brunch, Chloë wore a silky black button-down shirt, black trousers and gold heeled books.

With her blonde hair tousled into loose curls and her make-up stripped back, Moretz seemed to dress as a mini Posh Spice for the occasion.

Later in the day, the 21-year-old donned a white button-down shirt with a ruffled collar, a black jacket, black fitted trousers, and sparkly silver heels, for the Creative Coalition's Spotlight Initiative Awards Gala Dinner.

With a swipe of coral-hued red lipstick and her hair pulled into a bun, Moretz added some much-needed colour to her monochrome look and we for one couldn't love it more.

Of course, this isn't the first time Moretz has paid tribute to her 'mother-in-law'.

Last year, the actress wore a Victoria Beckham SS18 pink pinstripe suit to the Harpers Bazaar Women of the Year Awards in London, and has recently been spotted in Blighty wearing one of her navy-blue trench coats.

Fortunately, it appears the pair get on swimmingly, with Victoria last month taking to Instagram to poke fun at the Kick Ass star.

'@chloegmoretz what have u done!! 😂😂😂 kisses x' she captioned a photo of Brooklyn Beckham's shaggy hair do.

Chloë responded: 'Hahahah ohhhhh my god.'

Just imagine a fashion collaboration between Victoria and Chloë.
