George and Amal Clooney were amongst the glamorous guests arriving at the Royal Albert Hall in London on Monday evening ahead of the King's Trust 50th Anniversary Celebration.
She chose a gold sequin gown by Alexander McQueen for the occasion, which is of course, the Princess of Wales' go-to designer label. It's actually a gown she was pictured in last year, so it's a clear favourite, and it's from the Autumn/Winter 2007 collection - making it a vintage piece.
