All White On The Night! Debutantes Dazzle As They Are Introduced Into Society At The Vienna Opera Ball, While Brooke Shields Attends As The Date Of Austrian Billionaire

The ball is one of the most exclusive events in the Viennese social calendar and every year, Austria's most important men and women descend on the Wiener Staatsoper in Vienna. 

To kick-start the festivities, 186 debutantes and their partners dance the opening waltz, under the watchful gaze of the older guests, which this year included Hollywood star Brooke Shields, 50, who attended the glamorous gala on the arm of Austrian businessman Richard Lugner, 83., top right.
