DALLAS (KDAF) — Actress Margot Robbie has announced that she’s expecting her first child with husband Tom Ackerley, after being photographed in Italy with an outfit showcasing her exposed stomach and prominent baby bump.

The Barbie star is the latest A-lister to debut a baby bump in paparazzi photos. In recent years, the trend of using fashion to highlight and display a growing baby bump bas become a popular way for celebs, like Rihanna, Sofia Richie, and Hailey Bieber, to take control of their pregnancies.

Nick Drewe, trends expert and founder of online platform Wethrift, shares some insight on the choice for celebrities to highlight their baby bumps with their pregnancy fashion choices.

“Debuting a baby bump during outings where the paparazzi are likely to be on the lookout for photo opportunities is essentially an A-listers way of unofficially announcing an unconfirmed or rumored pregnancy to the rest of the world,” Drewe said. “Rather than covering up with oversized outfits and being careful of angles, they are instead embracing their bumps and choosing fitted clothing and styles that accentuate their stomachs, rather than covering them up.”

Where celebrities tread, the public will follow. These A-listers set the fashion trends for years to come, which means we can expect retailers to capitalize on this trend.

“We expect to see retailers with maternity lines following this emerging trend and continue to expand on more affordable options for pregnant people,” Drewe said. “Options that — while still maintaining comfort — focus on accentuating bumps and allow individuals to display them proudly.”
