Elmo is trading his usual cheerful personality for a decidedly icier attitude this Halloween. The beloved Muppet dressed up as Miranda Priestly from The Devil Wears Prada on Sesame Street on 27 October, delivering sharp fashion critiques to his Sesame Street neighbours. Elmo revealed his costume to his neighbours, complete with a white wig, glasses perched low on his nose and a black blazer over a white collared shirt.

The transformation quickly caught the attention of fans, particularly when Elmo stayed in character to deliver a sarcastic remark about an approaching pumpkin before turning his attention to Cookie Monster's blue fur. The costume and jokes were shared on Reddit, where users praised the unexpected crossover between children's television and one of cinema's most recognisable fashion editors.

Miranda Priestly's signature attitude

In the video, Elmo begins by asking viewers to guess his costume before revealing the complete look. The white wig, understated glasses and dark blazer recreate Miranda's distinctive appearance, but the real joke comes from Elmo adopting her famously dismissive manner.

When a pumpkin passes in front of him, Elmo remarks, 'Pumpkins. For fall. How groundbreaking.' The line adapts one of Miranda's best-known remarks from the original 2006 film, in which she responds to a suggestion about floral designs with the cutting observation, 'Florals? For spring? Groundbreaking.'

The original line became one of the film's most recognisable quotes because it captures Miranda's impatience with predictable ideas. By applying the same attitude to a traditional Halloween decoration, Elmo turns an ordinary seasonal image into an opportunity for fashion-world sarcasm.

A Cerulean Critique

Cookie Monster is also caught in Elmo's fashion-editor routine. When his blue fur becomes the subject of discussion, Elmo observes, 'Well, it's not cerulean. But, it works.'

Cookie Monster responds with confusion: 'Uh, thanks? Me think?'

The exchange refers to another famous scene from The Devil Wears Prada, in which Miranda explains the significance of the colour of character Andy Sachs's supposedly ordinary blue sweater. Miranda describes how the colour cerulean moves through high-fashion collections before eventually reaching everyday clothing, demonstrating how trends influence even consumers who believe they have no interest in fashion.

Elmo's remark reduces that elaborate explanation to a brief assessment of Cookie Monster's signature colour. Cookie Monster's uncertain response provides the comic contrast: while Elmo adopts Miranda's controlled, cutting delivery, his blue-furred friend appears unsure whether he has received a compliment or an insult.

The Devil Wears Prada and Its Influence

Miranda Priestly remains one of Streep's most recognisable screen roles. At the time of its release, the movie nabbed her an Academy Award nomination for Best Actress. Miranda's dry delivery and uncompromising standards became central to the film's appeal, making her an especially recognisable character for a Halloween parody.

Interest in the franchise has received another boost from The Devil Wears Prada 2, which brought Streep and co-stars Anne Hathaway, Emily Blunt, and Stanley Tucci back to the screen in 2026. The sequel revisits the fashion-media world while examining the changing landscape of magazine publishing.

Fans embrace Elmo's unexpected fashion era

The Reddit discussion surrounding the reveal was largely enthusiastic. Commenters praised Elmo's resemblance to Miranda, while others joked about how naturally the character appeared to fit into the fashion-editor role. Some also extended the joke by imagining how Elmo might respond to other Sesame Street characters.

Elmo has worn other costumes in previous Sesame Street Halloween segments, including a pirate outfit, a witch costume, and a spaceman character called Galactic Stan. The Miranda Priestly look is a more specific pop-culture reference, relying on a famous performance and dialogue that many adult viewers recognise immediately.

With Halloween approaching, Elmo's transformation has given Sesame Street fans a playful take on fashion's most intimidating fictional editor. Cookie Monster may not have asked for a style review, but in Miranda mode, Elmo clearly considers even his closest friends fair game.
