Three dresses worn by Princess Diana are currently being shown in Beverly Hills and will go on auction on Sept. 6-8.Martin Nolan, Julien’s Auctions executive director said: "Diana in her own right could have been a Hollywood star.

She was so elegant, so gorgeous, so in touch with people, she had such great charisma and poise, and people gravitated towards that, and they loved her. In her own sense, she was an actress because she had to act in the way of the royal family's expectations. At that time, when she was wearing these dresses, she was destined to be the future Queen of England."

"British royalty is what people look up to. And they set trends and they look upon them as the trendsetters and then Hollywood would follow," he continued.

Nolan said: "Princess Diana wore this dress on three occasions in 1989 and in 1991, she was at the Odeon Cinema in Leicester Square in London to the premiere of the movie “Hot Shots!” starring Charlie Sheen. Diana went to that event with the president of Hungary and his wife Zsuzsa. We estimate this dress 200 to 300,000 dollars."

"Diana is highly collectible. She was such a glamorous lady. She was the people's princess. She's also the mother of the future king of England. So that's really important as well when people buy items like this, the thinking of the future value and how they will appreciate," he concluded.
