In July 1999, the very first White Tie & Tiara Ball was held.
Set amongst 37 acres of rolling English countryside next to Windsor Castle, the annual gala raises money for the Elton John AIDS Foundation.
As the latest Ball approaches (on Thursday), the organisation expressed gratitude to the ''fabulous sponsors who make this possible.''
This years sponsors include EJAF's main sponsor Chopard, support by Jo & Raffy Manoukian, Neuro and media sponsor OK! magazine.
The foundation also sent out special thanks to Audi, Grey Goose, Indoor Garden Design, Veuve Clicquot, Ty Nant and MIG Security, not to mention their Official Hotel: Grosvenor House.
