Princess Diana and Kate Middleton’s similar styles

Kate Middleton and Prince William struck a very similar pose in their 2010 engagement photo to that of Princess Diana and Prince Charles in 1981. Both princesses-to-be showed off the same dazzling 18-carat sapphire diamond ring.

On July 29, 1981, a 20-year-old Lady Diana Spencer wed Prince Charles at St. Paul's Cathedral. The princess-to-be wore a dress designed by David and Elizabeth Emanuel for her historic walk down the aisle. Thirty years later, Kate Middleton became the Duchess of Cambridge on April 29, 2011 in an Alexander McQueen dress by Sarah Burton.

Princess Diana attended a polo match in 1988 casually attired in jeans and a blazer. Years later while visiting Alberta, Canada in July 2011, Kate looked chic in a similar combo wearing a Smythe blazer and J. Brand jeans.

While visiting British troops in 1995, Princess Diana wore a Jackie O. inspired pink suit by Gianni Versace, and in May of 2012, the Duchess wore a rose pink dress by Emilia Wickstead and L.K. Benett heels to a garden party held at Buckingham Palace in celebration Queen Elizabeth's Diamond Jubilee.

With a nod to both her mother-in-law and her mother, Carole, from whom she borrowed the sapphire Reiss dress, The Duchess of Cambridge looked radiant as she gave her first public speech at EACH's Treehouse Children's Hospice in Ipswich, England.

Princess Diana chose this strapless chiffon dress by Catherine Walker in 1987 for the Cannes Film Festival (and again to the 1989 London opening of Miss Saigon!). Kate wore a similar look when she made an appearance at the BAFTA 'Brits to Watch' event in a pale lavender Alexander McQueen gown.

Princess Diana (in 1986) and Kate Middleton (in 2005) both chose to keep warm while on the slopes in red puffer jackets and practical head gear.

Keeping with the English tradition of fabulous fascinators, Duchess Catherine followed in the footsteps of her late mother-in-law by wearing a feathered hat to a wedding in 2006. Diana was seen in a similar look while at an event in Pembrokshire in 1981.

Princess Diana arrived at the Royal Albert Hall in 1990 wearing a chic black and white skirt suit. In 2011, the Duchess of Cambridge chose a similar military-inspired ensemble by Alexander McQueen while visiting a community center in Birmingham.

Princess Diana met with Mother Theresa in New York in 1997 wearing a simple white suit. Kate Middleton went for a similar look in September 2012 choosing an Alexander McQueen skirt suit while touring Singapore's Rolls Royce factory.
