This afternoon, the Duke and Duchess of Sussex debuted their newborn son, Archie Harrison Mountbatten-Windsor, to the world.

For the highly-anticipated reveal, the 37-year-old new mum dressed her post-baby bump in a sleeveless trench dress by Vogue Fashion Fund prize winner, Grace Wales Bonner.

The sartorial move further demonstrates Meghan’s independent approach to royal life and of course, only reminds us of her fashionable know-how.

She accessorised the designer ensemble with co-ordinating suede heels, a Jennifer Meyer turquoise necklace and kept her hair in loose waves - a far cry from her polished bun.

The Duchess of Sussex was widely praised online for highlighting her post-baby bump with social media users crediting her ‘body-positive message’.

While others joked that the royal made a brave decision choosing to wear white so soon after welcoming a newborn child.

The former actress previously wore a similar ensemble for a trip to the Nelson Mandela Centenary Exhibition in London on July 17, 2018.

For the outing, she demonstrated how to tackle a great British heatwave in a blush pink sleeveless trench by Canadian brand House of Nonie.

In a less-than-surprising statement, she teamed the protocol-breaking look with a co-ordinating £600 clutch by Mulberry and £520 Dior shoes.

But some royal fans were left disappointed that the self-confessed feminist decided to participate in the royal baby photocall just two days after giving birth.

One wrote [sic], “Just when I was cheering Meghan Markle for avoiding a royal baby perp walk in a fancy dress & heels as Kate always does, she shows up in a white(!) dress and stilettos.”

“All I wanted was for Meghan Markle to come on TV with her hair in a towel, face mask on, wearing a juicy tracksuit eating a snickers,” another added.

The publicity move is a first for the royal family however, as the Duchess of Cambridge gave same-day Lindo Wing exits for all three children.
