The bold look comes on the heels of Robbie wearing several daring outfits during the press tour for the film.
Margot Robbie's fashionable streak continues -- this time, on the late-night circuit!
The actress, 35, made her debut on Late Night with Seth Meyers on Tuesday, Sept. 16, alongside her A Big, Bold, Beautiful Journey costar Colin Farrell in a beige dress with a sculptural, shell-inspired bust that looked like the perfect spot to secretly store her wares.
"Shout out to the dress, let's get it out of the way," Meyers told the actress. Robbie, demonstrating how wide the bust of the dress was by putting her hands into it, replied, "It's my shoplifting dress."
Farrell also had another joke to contribute to their banter and added, "Shout out to Margot sending me a picture of it earlier, thankfully, because I was going to wear something very, very similar."
"That would have been embarrassing. You wore the shell dress, I wore the shell dress," Robbie said, before Meyers clarified, "It was gonna be a shell sweater. But it was very similar from the waist up."
The Suicide Squad star's bold shell-inspired dress is far from the only look that she's turned out in recent days. Robbie has wowed in several skin-baring looks months after welcoming her first child with husband Tom Ackerley during the press tour for A Big, Bold, Beautiful Journey.
On Sept. 11, the actress wowed in a dazzling Armani Privé naked dress with pink, purple and silver jewels for the U.K. premiere of A Big, Bold, Beautiful Journey. The daring elements continued with a sexy back detail that featured more jewels in between her shoulder blades before extending down into a long strap that connected to the bottom of the dress.
For the Sept. 15 premiere of A Big Bold Beautiful Journey at AMC Lincoln Square Theater in New York City, Robbie dazzled in a vintage black and white Thierry Mugler Couture dress. The dress, which came from the brand's spring/summer 1998 collection, emphasized her cleavage and featured slits that showed off her toned legs.
During the New York City premiere of the movie, the actress told Entertainment Tonight that her sexy looks have been "for the girlies."
"It's like a fun opportunity to kind of express yourself on the red carpet, I guess? I don't know. Honestly, for me, I'm doing it for my girlfriends," she told the outlet. "I'm just hoping they get a kick out of it. That's why. Every time we get glammed up, I'm like,'I just can't wait for my girlfriends to see this.'"
