This caused much confusion among the mourners gathered at the funeral.
Audrey asked Mary whether it was a religious outfit, but Mary said only Norris would understand.
Viewers were equally as baffled.
Ange said: "Wtf is Mary up to wearing that?!"
Chaser Jenny Ryan tweeted: "MARY BEING ICONIC ALERT."
Matt tweeted: "Is it me? Or is Mary dressed as Princess Leia from Star Wars for Norris' funeral?"
Bernadette added: "Can we just all take a moment to talk about Mary’s outfit."
Lucy said: "Why is Mary dressed as Leia?"
Nerrad commented: "Why is Mary dressed like Princess Leia from Star Wars?"
Carly said: "WHY is Mary dressed as Princess Leia from Star Wars for Norris’s funeral!"
And Cara wrote: "Got so many questions about Norris funeral why is Mary dressed as Princess Leia and why is there a stapler on top of the carriage."
However, in a letter left by Norris, he revealed as a joke he once told Mary how much he would love it if at his funeral she wore a Princess Leia costume.
He added: "But not even you would fall for that."
