The wedding dress Diana wore to marry Prince Charles is an iconic dress. On the 29th of July 1981 millions watched as shy Lady Diana Spencer entered St. Paul’s Cathedral to marry the heir to the throne. Let’s discover all the secrets of Princess Diana’s wedding dress!
I found particularly useful the book written by the designers chosen by Diana to make her wedding dress: A Dress for Diana by David and Elizabeth Emanuel.
