According to a royal insider, the duchess-to-be has chosen a hand-stitched beaded gown which boasts a serious price tag of £100,000 (Dhs497,185).
The source revealed: "It sounds a lot but this is the wedding of the year and hundreds of hours of manpower have gone into making it, almost all by hand."
Though it's not the first time the former actress has worn a dress courtesy of the London-based fashion house.
For the soon-to-be newlywed's engagement photographs, Meghan donned a now-famous £56,000 (Dhs278,423) sheer dress by the couture label.
According to The Sun, the former Suits actress has had regular fittings with Australian design duo - Tamara Ralph and Michael Russo - in the run-up to the nuptials.
A source told the tabloid: "Like most brides, Meghan has been on a bit of a health kick and has lost a significant amount of weight."
They added, "Accordingly, she’s had at least three fittings at Kensington Palace, with the dress taken in each time."
Despite the endless speculation circulating the royal wedding, Prince Harry is determined to keep his bride-to-be's dress "a complete surprise".
The source added,"He is so excited about the wedding and is being remarkably traditional about everything."
According to Kensington Palace's newly-released statement, the first time the nation will catch a glimpse of Meghan's dress is when she departs from her overnight location.
Joined by her mother, Doria Ragland, the 36-year-old will travel by car to Windsor Castle where she will be joined by the bridal party before heading down the aisle.
Meghan will later change into a second wedding dress for the couple's private reception which will be hosted by Prince Charles at Frogmore House.
