Background

The 2026 Halloween season follows a year dominated by Christopher Nolan’s 'The Odyssey,' which became Universal’s highest-grossing film with $1.684 billion in global revenue. This cultural impact extends into costume trends, with Agamemnon ranking fourth in Google’s search data. Additionally, the horror film 'Obsession,' which cost $750,000 to make, has grossed over $500 million, driving significant demand for its characters. The broader trend reflects a shift in consumer behavior, with fewer Americans planning to dress up, but those who do are opting for more creative, high-impact, or nostalgic looks.

How outlets are covering it

BBC and Variety emphasize the influence of major film releases like 'Obsession' and 'The Odyssey,' as well as pop culture icons like Dolly Parton and Charli XCX. Google’s data, however, highlights unexpected viral trends like 'NeeDoh' and 'Buddy the Unicorn,' suggesting a divergence between mainstream media coverage and actual consumer search behavior. The New York Post notes that fewer than a quarter of Americans plan to dress up, but Gen Z and millennials are 10% more likely to participate, favoring unique or DIY costumes. BBC also highlights a 'whimsical' fashion trend, including gargoyles and moths, which contrasts with the horror-focused trends reported by Google and Variety. All sources agree on the popularity of 'Obsession' and 'The Odyssey,' but differ in their emphasis on nostalgia versus viral internet phenomena.

Why it matters

Halloween costume trends reflect broader cultural shifts in entertainment consumption, with horror films and viral internet phenomena driving consumer behavior. The rise of DIY and whimsical costumes indicates a move away from fast fashion and toward personalized, creative expressions. Additionally, the popularity of nostalgic costumes suggests a desire for escapism and glamour, reflecting current societal moods. These trends also impact retail, with costume shops reporting high demand for specific characters and outfits, influencing inventory and marketing strategies.

What to watch

As Halloween approaches, expect continued demand for 'Obsession' and 'The Odyssey' costumes, as well as viral trends like 'NeeDoh' and 'Buddy the Unicorn.' Retailers may see increased sales of DIY materials and whimsical costumes, particularly among Gen Z and millennials. Nostalgia-driven costumes, such as Buffy and Hilary Duff, will likely remain popular, while political figures like Donald Trump and Vladimir Putin may see a surge in demand. The trend toward 'extraordinary' looks over frightening ones suggests a shift in consumer preferences, with a focus on glamour, escapism, and dark humor.
