Perrie Edwards told the Daily Mirror newspaper: "I definitely want long sleeves. I know exactly what I want, so I'm designing it and getting it made from scratch."
"Not that I can draw ... I'm getting Jade to do it. She's going to draw it and I'm going to take it to somebody to make."
Meanwhile, Perrie has already figured out how she wants her makeup to look on the big day.
She added: "I'm gonna have natural makeup, not too natural. I don't want to be a natural Nancy ... but nice, light eye shadow with a nude lip."
