Zoë Kravitz serves underboob in sultry Saint Laurent at 'The Batman' premiere
Watch: Robert Pattinson and Zoe Kravitz attend The Batman screening
Zoë Kravitz and Robert Pattinson shut down the red carpet last night at the London premiere of The Batman.
Kravitz seemed to channel her on-screen Catwoman character, exuding edgy elegance in a figure-skimming, floor-length black gown that flashed her underboobs.
The incredible dress is a Saint Laurent number designed by the company's creative director, Anthony Vaccarello, and featured a square neckline, halterneck straps and bold underboob, cut-out detailing.
The actor, 33, who plays Catwoman, AKA Selina Kyle in the film, has had a long affiliation with YSL and is also a global makeup ambassador for the luxe brand.

The Big Little Lies actor teamed the scallop-edged halterneck with simple black and pearl earrings, black heels and wore her hair in a slicked back style with paired-back make-up, allowing her dress to take front and centre.
The outfit offers further proof Kravitz is using her wardrobe to embody her Catwoman character with the risque look appearing to be straight off the set.
Kravitz isn’t the only celebrity to experiment with underboob garments recently. Many celebrities have been ditching conventional cleavage in favour of underboob flashing style.
Bella Hadid recently tested out the trend wearing a super slinky under-breast revealing top and extreme low-rise skirt as part of her partnership with Michael Kors.
Sister Gigi Hadid has also flirted with the craze in a flesh-flashing cutaway gown worn to the Oscars after party in 2015.
Meanwhile Rihanna is basically leader of the underboob pack, regularly flashing her lower cleavage in the coolest of crop tops.
Pattinson joined his leading lady at the glitzy event, where he looked equally stylish in an oversized, speckled grey suit layered over a black turtleneck.

He isn't the first celebrity to turn to turtleneck style on the red carpet recently, with Prince William causing quite the stir last year after donning the fashion-foward look.
Attending the Earthshot Prize awards alongside the Duchess of Cambridge, the royal wore a recycled green velvet blazer from Reiss, paired with a turtleneck jumper.
As soon as the pair arrived at the awards fans flooded social media, fawning over Prince William's fashionable ensemble.

Meanwhile earlier this month Kravitz spoke out about the trolling she experienced following last September's Met Gala.
The award-winning actor arrived on the red carpet in a traffic-stopping diamanté net, naked dress, with a rhinestone thong and black high heels.
But while fashion lovers were delighted by the daring look, with many media outlets adding her bold style to 'best dressed' lists, some were not so complimentary.
Last week, however, the Big Little Lies and The Batman actor explained how it felt to be mocked, and why she left Instagram a week after the gala.
At the time, she hit back at critics, saying: "“Being uncomfortable with the human body is colonisation / brainwashing. It’s just a body. We all got em."
Then in an interview for the March issue of Elle Magazine, Kravitz admitted: "The fact that people don’t think what they say affects a celebrity because you’re not a person to them is crazy.
"I’m a human being. I want to f—king defend myself.”
Meanwhile science recently confirmed what our Twilight-loving selves have known for years that Robert Pattinson is the most handsome man in the world.
Research into what constitutes the "perfect face" has found the actor to be 92.15% "accurate" to the Golden Ratio of Beauty Phi, which measures physical perfection.
His eyes, eyebrows, nose, lips, chin, jaw and facial shape were measured against other celebrities and his make-up meant he came closest to the ancient Greeks’ idea of perfection.
