American Idol judge Katy Perry has criticised Meghan Markle’s wedding dress.

Perry told Entertainment Tonight that the Duchess of Sussex’s Givenchy gown needed “One more fitting”.

The pop star suggested it fell short of the bridal look Alexander McQueen designed for the Duchess of Cambridge’s marriage to Prince William in 2011, adding “Kate won!”.

Despite her criticism, Perry said she was “So happy” for the couple.

“I would have done one more fitting,” Perry quipped of the Duchess of Sussex’s Givenchy gown.

The minimalist boat neck, which framed Ms Markle’s shoulders and emphasised her waist, heavily contrasted with the Duchess of Cambridge’s high V-necked lace-covered gown in 2011, which was designed by Sarah Burton of Alexander McQueen.

Perry made the remarks while speaking to Entertainment Tonight’s Lauren Zima during night one of the American Idol finals.
