The pairing style of the duchesses sent everyone into a frenzy, but their coordination was informed on purpose.
According to Vanity Fair, a real source claimed that Meghan was deliberately wearing a loose dress so that her baby hit would not become the main story.
His source said: "Since Meghan and Kate were making commitments on the same day, I imagine that some thought of their outfits.
"I think it's probably fair to say that Meghan's outfit was carefully planned so that it would not take away from what they were doing by showing her baby blow."
Express.co.uk has contacted the Kensington Palace to provide a comment.
Meghan's dress was a Monaco Club number, while Kate's jacket and skirt were Paule Ka's and a dress that she had put on twice before.
The first time he used the two pieces in 2012 for a real engagement at the Middle Temple in London.
When she wore the festive red suit six years ago, Kate combined it with a black patterned blouse and wore her hair in swollen curls around her shoulders.
This time, the duchess allowed her attire to talk all the time as she swept her brunette from her face with a voluminous ponytail.
Catherine very rarely wears her hair, but this time she chose to do it keeping her braids on an informal side and with a neat pony.
She completed her elegant look with a pair of black suede heels with a comfortable thick heel and a small matching handbag.
Meanwhile, Meghan was wearing a knee-length loose dress, revealing only a glimpse of her baby's bulge under her jacket.
Meghan's coat may have coincided with her dress, but the burgundy stopped there when she combined the look with black boots with a pointy toe.
And the dukes even combined with their hairstyles, since Meghan had also rocked a low ponytail that morning.
The Duchess of Sussex visited Hubb's community kitchen to see how the funds raised by Together: Our Community Cookbook are already making a difference.
It is expected that in the coming months Meghan, Kate, Prince William and Prince Harry will make more solo commitments as the brothers divide their offices to focus on their individual projects.
