According to museum curator Matthew Storey, this dress was one of the princess' favorite looks.
On a visit to Egypt, the late royal did a bit of sightseeing.
Who could forget this moment at the Vanity Fair party? The look has since been named the "Revenge Dress."
Before her death, the royal supported the American Red Cross at an event in Washington, D.C.
On a trip to Northwick Park & St. Mark's Hospital, Princess Di celebrated the laying of foundation stone for the new children's ambulatory care center.
Several weeks before her death, Princess Diana made one of her last humanitarian trips. Specifically, she visited Bosnia to show support to victims who had been injured by landmines.
In her final public appearance, Princess Di viewed a performance of Swan Lake at the Royal Albert Hall.
