In keeping with tradition, compliance with ball etiquette is strictly required. Although Rudolf Kalmar, former president of the Press Club, once joked to a newspaper (Die Presse) about how strict the Concordia Ball was regarding its adherence to formality, he also noted that 'the ball speaker's speech carried the same weight as a formal policy statement. The way the cosmopolitan city respected the Concordia Ball, was the respect to it's mind.'
In keeping with the venue and ambience of the ball, the following dress code applies:
Ladies: Floor-length evening dresses
Gentlemen: Dark tuxedo, dinner jacket, military uniform and bow tie
The ball committee reserves the right to refuse entry to any guest who does not honour these dress rules.
