Kate Middleton’s Blue Issa Engagement Dress Crowned Most Iconic Dress of All Time

Kate Middleton's engagement dress has topped the list of the Most Iconic Dresses of All Time.

The Duchess of Cambridge's Blue Issa dress, that she wore to announce her engagement to Prince William, beat Jennifer Lopez's tropical-printed Versace number and the stunning red gown that Julia Roberts wore in Pretty woman, to take the crown.

According to the list, compiled by leading style psychologist Kate Nightingale, the hue of her royal blue dress helped her to win because it apparently "symbolises that she is trustworthy and dependable".

The accolade comes just weeks after the fashionista was named Vanity Fair's World's Best Dressed Woman.

The prestigious list also featured other fashion icons including Audrey Hepburn and Twiggy.

Speaking about the gowns, Nightingale said: "Looking back through the history of fashion, the common factor among the iconic outfits that stick in our minds is colour and vibrancy.

"From Julia Roberts' rags-to-riches red dress in Pretty Women to that daring green dress J-Lo wore at the Grammys, the Hollywood A-list knows exactly how impactful colour can be when it comes to grabbing attention."
