Christina Aguilera as a seductive nurse
Among the countless costume ideas, there is one that appears every year and has long since lost its originality: the nurse costume. But Christina Aguilera managed to breathe new life into this classic – and caused quite a stir. Her look is strongly reminiscent of the iconic album cover of Enema of the State by rock band Blink-182 – was that her inspiration? At her side was a charismatic “doctor” – none other than her then husband Jordan Bratman, from whom she split in 2010. But Aguilera remained in the spotlight after that and wowed audiences in 2021 with a song for the hit movie The Addams Family 2.

Margot Robbie and Sophia Kerr as the creepy twin from The Shining
in 2016, Margot Robbie brought the iconic Harley Quinn to life – but although the costume became an absolute must-have, she wasn’t a fan of it herself. Instead, she and her friend Sophia Kerr opted for a much scarier outfit: the pair dressed up as the iconic twins from The Shining – complete with blood-spattered dresses and terrifying looks. Year after year, the pair continue to wow with creative costumes, including an homage to The Wolf of Wall Street and Robbie’s portrayal of Sharon Tate in Once Upon a Time… in Hollywood.
