Royal Wedding: Clues About Meghan Markle's Dress Emerge

Inside Edition also tried a similar wedding cake.

Days before the royal wedding, some clues about Meghan Markle’s dress may have slipped out.

An eagle-eyed photographer in London snapped rolls of ivory silk labeled "Ralph & Russo," the British designer behind the dress worn by the "Suits" actress in her engagement photos. 

Inside Edition went to Joel & Sons Fabrics, the official supplier to the royal family, to try on their materials.

Inside Edition Royal Wedding Correspondent Amanda Holden also tried out delicacies from London’s Violet Bakery, which was chosen by Meghan Markle to make the lemon elderflower wedding cake. 

She said the cake, which will be made by Claire Ptak, was very good. 

Ptak, who was raised in California, focuses on the use of seasonal and organic ingredients in her cakes. She moved to London 13 years ago, where she now owns the popular bake shop.

Elderflower originated during the Victorian era, paying homage to Prince Harry's regal roots. 

Markle and the pastry chef have a history. In 2015 the princess-to-be interviewed Ptak for her now-shuttered lifestyle blog, The Tig.
