16 It-Girl-Approved Halloween Costume Ideas
How does one find the perfect Halloween costume that is equal parts unique, alluring and impressive? Turn to the It girls of the fashion world, of course.


Anyone who knows me will tell you how much I love the month of October. Between the long walks around town with a hot chocolate in hand to planning my cold-weather wardrobe, there are so many things I look forward to. One October event that often gets me stressed, however, is Halloween. I love the sweet treats, horror films, and of course, the parties. But the thought of finding a costume that's fun, looks chic, but also doesn't break the bank often fills me with a sense of dread.
To avoid the anxiety I feel year after year, for 2025, I’ve decided to plan ahead. And how does one find the perfect Halloween costume that is equal parts unique, alluring, and impressive? Turn to our seasoned panel of experts in everything cool, the It-girls of the fashion world, of course. I’ve taken a look back at my favourite celebrity It girl Halloween costumes to draw some inspiration I can wear to the number of spooky parties and events I have planned this year. This year specifically, I’m looking for costumes that don’t require a lot of work, but still look cool, stylish, and set me apart from the crowd.
