The phrase refers to costumes specifically designed for toddlers within the eighteen to twenty-four month age range, typically coinciding with Halloween celebrations. These articles of clothing are intended to allow young children to participate in festive activities such as trick-or-treating or costume parties. An example would be a miniature firefighter or pumpkin-themed garment sized for this specific age group.
Providing appropriate garments for toddlers during such events carries significance. Comfortable and safe apparel allows for unhindered enjoyment of the holiday. Historical context suggests that costume traditions have evolved from protective rituals to contemporary celebrations, with adapted clothing catering to all ages, including this vulnerable demographic.
