Earlier this year, fellow retailer Next also had an advert for blue skinny jeans banned because the model’s pose made her look “unhealthily thin”.
The ASA said the advert emphasised the thinness of the model’s legs using camera angles, and deemed it “irresponsible”.
Next said it disagreed with the advertising watchdog’s decision and said the model, while slim, had a “healthy and toned physique”.
It is not just fashion adverts that have been banned by the ASA recently.
Earlier this month, an Instagram post by TV personality Gemma Collins which showcased a weight-loss drug and app was banned.
It is illegal to advertise prescription-only weight-loss drugs and Ms Collins’ was one of nine adverts banned in a crackdown on this content by the ASA.
Ms Collins told the ASA’s investigation she accepted her posts had promoted the Yazen weight-loss service and app and she would follow guidance in future.
