Princess Eugenie is marrying her long-term partner Jack Brooksbank at St George’s Chapel in Windsor.

And, alongside the Royal Family and celebrities among the 850 guests at the ceremony, many have tuned in from around the country to get a glimpse at the ninth in line to the throne’s royal wedding dress, has been designed by Peter Pilotto and Christopher De Vos.

The designer duo, who founded the British based label Peter Pilotto in 2007, are known for its innovative textile design, paired with a modern feminine silhouette.

Eugenie met the designers when she was co-hosting an event in support of women artists – and has been wearing designs by the brand ever since, according to the royal family.

Eugenie, Pilotto and De Vos worked closely on the design of the dress – and have included a number of motifs and secret symbols that are important to the royal.

“The symbols are a Thistle for Scotland acknowledging the couple’s fondness for Balmoral, a Shamrock for Ireland as a nod to the Bride’s Ferguson family, the York Rose and ivy representing the couple’s home,” reveals an official royal source.

“Peter Pilotto and Christopher De Vos have reinterpreted these symbols in a garland of rope like motifs, woven into a jacquard of silk, cotton and viscose blend.

“Once the artwork was completed, it was translated into a jacquard weave in the Como region of Italy. The result is a very modern looking fabric using a highly intricate weaving technique.”

Eugenie has accessorised her gown with the Greville Emerald Kokoshnik Tiara, lent to her by Her Majesty The Queen. The tiara was made by Boucheron for Mrs Greville in 1919 in the fashionable ‘kokoshnik’ style popularised in the Russian Imperial Court.

And, as well as her very expensive ‘something borrowed’, Eugenie has also donned a pair of diamond and emerald drop earrings – which were a gift from her new husband, Jack Brooksbank.
