The airline placed advertisements online for an Oslo recruitment day event for cabin crew members and specified the women should wear short skirts while men should wear "business suits," TheLocal.no reported Wednesday.
"We believe that it is contrary to law that there should be different clothing requirements for men and women," Carl Fredrik Riise, an advisor for the anti-discrimination ombudsman, told the DN newspaper. "It discriminates between applicants on the basis of gender."
The advertisement was amended Tuesday to recommend members of both genders come to the event dressed in "business wear."
However, an advertisement on the website for a similar event in Romania still had different clothing guidelines Tuesday for men and women.
"For Ladies: business Suit, knee length skirt (with skin colour stockings or no stockings) and short sleeved blouse. Hair neatly tied back with appropriate make up," the advertisement reads.
