It's not just dresses she wears though - last year Amanda appeared in a slinky jumpsuit, leaving some fans hot under the collar when she appeared in a video and unzipped it.
And some of her dresses on Britain's Got Talent pushed the boundaries so much, the show got Ofcom complaints.
Amanda brushed off the interest in her outfits while talking to The Sun last year saying it's better to be "overdressed than underdressed".
She insisted: "It’s hilarious how much controversy my outfits have caused — people have got so much time on their hands.
“I mean, no one really paid much attention to what I wore when I was in my twenties or thirties. I enjoy it, it’s all good fun.
"I would always rather be overdressed than underdressed for any situation. That’s been a general rule for me since I was about five."
