The wedding will be split into two, much like William and Kates," an insider told Us Weekly, "so both Meghan and Harry will have second outfits."
According to royal correspondent Katie Nicholl via Vanity Fair, both dresses will be custom-made. Sources reveal that there will be "a traditional bridal gown for the ceremony and reception, and a glamorous, more sophisticated dress for the evening.
"Meghan can't wait to surprise everyone," the source said, "especially Harry."
In an exclusive interview with Express.co.uk, one of the UK’s leading bridal designers and couture fashion experts, Raishma addressed Royal traditions.
Meghan is likely to follow royal traditions, with the wedding dresses of both Kate Middleton and Princess Diana both featuring covered arms and shoulders and long trains.
The fashion expert said the key elements of a royal wedding dress have always been the same: elegant, modest, and with fairy tale magic.
Ralph & Russo
Although it is a rumour, The Daily Mail have confirmed that Meghan's wedding dress cost £100,000 and was paid for by Prince Harry's family. They reported that the future Royal bride will wear hand-stitched, beaded design made by British couturiers Ralph & Russo.
Ralph & Russo have been odds-on favourite for the commission since Meghan wore a £56,000 semi-sheer black evening dress from the label for her official engagement portrait.
Earlier this week, the Ralph & Russo haute couture atelier team were seen visiting the Royal School of Needlework, which was responsible for the bespoke lace on the Duchess of Cambridge’s wedding dress and boasts a long association with the Royal Family.
