Amanda Holden's revealing dress on Britain's Got Talent prompted over 600 complaints.
Her outfit on last month's live shows resulted in 650 official objections to TV regulator Ofcom.
However the watchdog has rejected the complaints and ruled out launching an investigation.
They said in the statement that the dress "would not have exceeded most viewers' expectations".
Ofcom added that "while some outfits were revealing, we considered it was appropriately scheduled".
Amanda will no doubt be over the moon with the news.
Speaking ahead of the live shows, she said if her outfits didn't get complaints, she was doing something wrong.
“I can’t wait to wear my dresses. They are very flattering, very feminine and a few are… what you would expect," Amanda said.
She told The Sun newspaper: “None of them have been worn before, which is the main thing for me
“I like to know no one six foot tall and skinny has worn it on a red carpet before. That’s why we wait for Cannes to finish before we start choosing."
And Amanda quipped: “Will people be complaining to Ofcom? I hope so, I really do. I haven’t done my job if they aren’t.”
"While his actions could be seen as offensive to some, we found they were justified by the light-hearted, comedic context," Ofcom commented.
