Despite objections, a young woman had to wear a sign stating her name, chest measurement and cup size while working at the Change chain’s largest store in the northeastern town of Sundsvall.
The Swedish Labour Court said on Wednesday the requirement was discriminatory and the woman’s dignity had been “violated”.
According to the ruling, the company used the badges to show that it had a wide range of products, and to make the issue of bra sizes “less dramatic” for customers.
“It’s a pleasing judgment… It’s also a great victory for the integrity of all employees,” a spokeswoman for the Commercial Employees’ Union, Jaana Paalsson, told Swedish news agency TT.
Change was ordered to pay 50,000 kronor ($A7,470) in damages, as well as the plaintiff’s legal fees.
