Sarah Ferguson, Duchess of York, 58, married Prince Andrew, 57, on 23 July 1986 at Westminster Abbey in London, England. 

Her dress was designed by Lindka Cierach, British couturier and fashion designer, and was made from ivory duchesse satin.

Lindka has since made dresses for a number of other notable members of the British royal family, such as Kate Middleton, Duchess of Cambridge.

The gown was heavily beaded, especially over the bodice, with symbols including hearts (to represent love) and waves, a homage to Prince Andrew’s career in sailing. 

It had a 17 foot long train which had Prince Andrew and Sarah’s initials sewn into it in silver beads. 

Lindka has since described the making of the dress in an interview.

She told People magazine: "The most important thing to me was that Sarah loved it."

“I wanted her sense of fun to come out in the dress.

At every stage, I wanted her to see and approve of what we were up to.”

The Duchess of York wrote about the dress in her 1997 autobiography, My Story.

She described the dress as “an exquisite creation I'd lost twenty-six pounds to fit into.

“Lindka was a genius; I knew she could make the most flattering gown ever, and she had.

“It was amazingly boned, like a corset,” she added of the dress’s structure.

The value of Sarah Ferguson’s jewellery collection was recently revealed.

An expert valued the redhead’s jewellery, including her engagement ring and wedding tiara.

In total it was said to be worth around £660,000, according to a gemologist. 

But can you guess what is Sarah Ferguson’s net worth?
