Cyber criminals have stolen the private details of potentially millions of Balenciaga, Gucci and Alexander McQueen customers in an attack.
The stolen data includes names, email addresses, phone numbers, addresses and the total amount spent in the luxury stores around the world.
Kering, the parent company of the luxury brands, has confirmed the breach and says it disclosed the incident to the relevant data protection authorities.
It said no financial information, such as card details, were stolen.
The firm also says it has emailed customers affected but has not said how many, or made any public statements about the hack.
