Katy Perry may have been the only person in the world who didn’t absolutely love Meghan Markle’s wedding gown, with the singer revealing she thought the Givenchy gown wasn’t a perfect fit for the new royal.

“I would have done one more fitting,” Perry told Entertainment Tonight when asked for her take on Meghan’s custom number from Givenchy’s British artistic director, Clare Waight Keller.

“I’m never not going to tell the truth! One more fitting, but I love you,” Perry said of Meghan.

The American Idol judge added that she preferred Kate Middleton’s 2011 Alexander McQueen wedding gown.

“Kate, Kate, Kate won, Kate won!” she admitted.

Perry, 33, had at least some nice things to say about Prince Harry, 33, and Meghan, 36, as people.

“I’m so happy for them, and, you know, I don’t know them from Adam, but it’s amazing what she’s doing with all this, her humanitarian efforts,” she said.

“You know, the fact that she’s a proud feminist, I love all that. I support her as another woman and love her and wish them both well.”

Markle’s dress was a otherwise a hit,  especially with her husband, who personally thanked Waight Keller for making his new wife look “absolutely stunning”.

“Afterwards, he [Harry] came straight up to me and said, ‘Oh my God, thank you. She looks absolutely stunning’,” the designer told The Sunday Times.

“I think it was just such a special moment for the two of them. They are so in love. I was thrilled to be part of it.”

Waight Keller also revealed she scored the design gig back in January this year, but managed to keep the exciting news a secret from everyone, including her husband, American architect Philip Keller.

Meghan had around eight meetings with Waight Keller to come up with the design for the gown, which took a huge team and an “enormous amount of hours” to create, the designer said.

“I think she had seen my work and knew what I did. I think she loved the fact that I was a British designer and working in a house such as Givenchy, which has got its roots in a classical, beautiful style.”

To maintain the “purity” of the dress, the dressmakers working on it were required to wash their hands every half an hour, she said.

“Over time you build up oils on your hand and when you work on something of such purity, absolute pure white, you need to keep it immaculately clean.”
