Zara ads have been banned by the advertising watchdog for featuring models deemed "unhealthily thin." This decision follows similar bans imposed on advertisements from Marks & Spencer (M&S) and Next, which also showcased models whose appearance raised concerns about promoting unhealthy body images. The watchdog's actions highlight an increasing focus on responsible advertising and the need to avoid portraying unrealistic or potentially harmful body standards in fashion campaigns. This series of bans signals a potential shift in advertising standards within the fashion industry.
