Princess Di's choice of clothing was unlike any other royal family member. The Princess made royal fashion accessible and easy to replicate. She redefined royal styling when she mixed style trends that were popular during her time and made them classy and timeless.

Who could forget her beautiful wedding gown? The white fluffy train that ran down the staircase when she made her way into aisle of St. Paul's Cathedral caught the attention of the world. The silk taffeta wedding dress had a train measuring 25-foot (7.6-meter) long and was designed by David and Elizabeth Emanuel. It featured blown out sleeves, bows, lace and pearl sequins and became a referral outfit for brides to follow.

If you thought that the wedding gown was most talked about outfit worn by Princess Diana, you're wrong! There was one particular black dress that Di wore that got its own label: The Revenge Dress. Princess Diana went from the elegant bride walking into the British royal family to a classy royal member when she wore the black off-shoulder dress.

The timeless piece of clothing, which could easily be replicated today, was all the media could talk about. And Princess Diana wanted just that. Popularly known as The Revenge Dress is figure-hugging, low-cut little black dress was worn to a Serpentine Gallery party in 1994 hours before Prince Charles's came out in the open to have cheated Diana with Camilla.

Diana's style statement could be defined as cool, casual yet royal and classy. It is safe to say that if Diana were alive today, she would be giving some epic fashion lessons to Kate and Meghan.
