The phrase refers to themed attire, specifically designed for young children, that enables them to emulate characters from the Trolls franchise during the Halloween season. This encompasses a wide array of commercially available outfits, often featuring brightly colored wigs and character-specific garments, allowing participation in trick-or-treating and other festive events.
Such themed apparel provides an avenue for creative expression and imaginative play within the context of a cultural celebration. It fosters a sense of engagement with popular media and allows for social interaction among children with shared interests. The availability of these costumes reflects the significant market demand for character-based merchandise tied to entertainment franchises and the widespread adoption of Halloween as a prominent cultural event.
