Two adverts by global fashion retailer Zara have been banned in the UK after the Advertising Standards Authority (ASA) ruled they featured models who appeared “unhealthily thin.”

The ASA said one model’s slicked-back hairstyle and shadowed facial features made her look “gaunt,” while another image showed “protruding collarbones” due to the model’s pose and a low-cut shirt design.

The watchdog deemed the adverts “irresponsible” and stated they must not appear again in their current form. It also instructed Zara to ensure future images are “prepared responsibly.”

As reported by Charlotte Edwards for BBC News, Zara has since removed the ads and claimed both models had medical certificates confirming their good health at the time of the shoot.

The ads, which appeared on Zara’s app and website, included a dress promotion where lighting and posing made the model appear disproportionately thin.
