The Tron: Legacy star, who became engaged to the comedian over Christmas (12), recently admitted she has been too busy to start planning her nuptials, and although she still has no idea when her big day will be, the bride-to-be reveals she will be hands-on when it comes to creating the perfect gown - and she hopes to convince her pals to help.
She tells Marie Claire magazine, "I don't know when we're going to get married, but it doesn't matter because we're going to be together forever.
"My dream is to have it close to New York. I love dressing up, and I want to design my own dress. I want to get friends involved because they have all protected and encouraged us."
The marriage will be both stars' second - Wilde divorced Italian royal Tao Ruspoli in 2011, while Sudeikis' union to screenwriter Kay Cannon ended in 2010.
