The ruling came from the State Labour Court in Cologne in the northwestern part of Germany in a judgement on the dress and grooming habits of airport security personnel, Britain's Daily Express reported. Being told to wear a bra and to keep fingernails to shorter than half-a-centimetre does not impinge on personal rights, ruled the court. The court's decisions will apply not just to workers at the Cologne airport but to all workplaces in North Rhine Westphalia region. Bras may only be dispensed with if a woman wears an undershirt. But workers scored one victory - they can wear wigs, the report said.
