Margot Robbie steps out in classic, comfy overalls for first outing since welcoming baby boy

Margot Robbie’s one stylish mom.

The “Barbie” star stepped out with husband Tom Ackerley and their baby boy on Monday in Venice, Calif., marking her first public outing since giving birth on Oct. 17.

The 34-year-old new mom looked comfy and chic in a lacy white Free People top ($78) and denim overalls ($128), finishing her outfit with red suede Aeyde Mary Janes ($326).

Robbie announced her pregnancy in July, showing off her baby bump in a crop top during a vacation in Lake Como with Ackerley, also 34.

Days later, she wore a polka-dot Alaïa dress for a Wimbledon date with her spouse.

And in September, she made her first (and only) red carpet appearance as an expecting mother, selecting a second-skin off-the-shoulder dress that accentuated her curves for the premiere of “My Old Ass,” a film she and Ackerley produced.

The couple wed in December 2016 in an intimate ceremony in Byron Bay, Australia, and are notoriously private.

However, in a June interview with the Times of London, the duo opened up about their relationship, with Ackerley revealing the one thing they fight about most: candy from their home countries.

The producer, who hails from England, said they specifically have disagreements over “whether Tim Tams or Penguins are better,” referring to the Australian and English chocolates, respectively.

He also revealed that the spouses spend all day together, working on their joint production company as well as their personal life.

“It’s seamless,” he said of their work/life balance. “We don’t have a toggle on, toggle off. It’s all become one thing.”
