American Apparel has been criticised by the advertising watchdog for an advert which "appeared to sexualise a child".
The Advertising Standards Authority (ASA) upheld two complaints about the advert, which appeared on the back cover of Vice Magazine.
It pictured a girl sitting on an office chair wearing a jumper, knickers and knee-length socks. She was posed with her legs up on the chair and her knickers were visible.
The latest ruling comes a week after the clothing brand fell foul of the ASA with campaigns featuring "gratuitous" images and the sexualisation of models who appeared to be under 16. American Apparel ran into similar issues with campaigns in 2009 and earlier this year.
The people who complained about the advert on the back of Vice Magazine objected that it was offensive and irresponsible.
