Fashion expert Donny Galella told New Idea, her outfit choice was no coincidence, all but confirming she was expeciting the couple's first child. It will be her first child with husband Prince Harry.
Another added: "I have a feeling that Meghan is pregnant.she's glowing and her face looks fuller to me...can't wait for them to announce it".
She was also spotted wearing a Camilla and Marc blazer matched with an Oroton cross-body bag to attend the Commonwealth Youth Forum reception in London in April.
The dress sent social media and tabloids into a frenzy.
But Meghan's mother Doria has been seen attending baby care classes, suggesting that she may move to the United Kingdom to help out.
According to the Daily Star, the former social worker was learning about breastfeeding, lactation consultancy, basic baby care, CPR and first aid through the Cradle Company in Pasadena, Los Angeles.
In that interview, Thomas had predicted Meghan and Harry would announce baby news sooner rather than later.More news: Nine climbers missing on Nepal's Mount Gurja after storm hits camp
And while they may have a schedule packed with official engagements, it's been reported that Meghan has brought her stylist and best friend along for the journey.

But some people can't help but notice there's something a bit amusing about the timing of the announcement - which comes immediately after this weekend's Royal wedding between Princess Eugenie and Jack Brooksbank.
The duchess opted to wear a Givenchy dress, covered by a loose-fitting matching coat. To cover up a baby bump, that's why!
Later this week Prince Harry and the Duchess of Sussex will move on down to Melbourne where they will be received by the state's politicians, meet youth leaders and take in the sites the city has to offer, including riding a tram.
And now they're starting a family!
The Duchess was seen exiting the plane carrying two large files that covered her stomach.
The tour coincides with the Invictus Games in Sydney, which runs from October 20-28. Meghan, wearing skinny black trousers and a black, burgundy trimmed coat, was smiling and clutching folders, while Harry gave a thumbs up to bystanders.
