The TV watchdog has said that it will not be taking any further action as the judge’s outfit “would not have exceeded most viewers' expectations.”
An Ofcom spokesperson added: “We carefully assessed complaints that dresses worn by judges were inappropriate for a pre-watershed audience.
“We recognise that the dresses had potential to offend some viewers during what is a family show.
"However, while some outfits were revealing, we considered it was appropriately scheduled and would not have exceeded most viewers' expectations.”
Ofcom received a total of 683 complaints over the course of the series, which were mostly about Holden’s wardrobe.
Fellow judge Alesha Dixon’s attire also received a number of complaints, as did David Walliams for dropping his trousers in front of Simon Cowell.
Holden, 46, sparked controversy by wearing a very low-cut Julian Macdonald dress during the live semi-final earlier this month, which many viewers dubbed “inappropriate.”
“What the hell is Amanda wearing on BGT, totally NOT suitable #BGT #BritainsGotTalent,” one viewer wrote on Twitter.
“#BritainsGotTalent Half term hols with kids watching- sort yourself out Amanda Holden - not good!” posted another.
Other viewers couldn’t see why such a fuss was being made over a dress, with one person writing: “Love how everyone is going metal over Amanda's dress... it's a bit of cleavage, grow up. Is her body. Not yours #BritainsGotTalent.”
