The phrase refers to attire selected for the Halloween holiday, designed specifically for adult females and sized to fit individuals who typically wear extra-large clothing. An example includes a plus-size superhero costume, available in an extra-large size to comfortably accommodate a larger body frame.
The availability of such attire is significant as it promotes inclusivity and body positivity. It ensures that individuals of all sizes have access to clothing that allows them to participate fully in seasonal celebrations and social events. Historically, sizing options were limited, excluding a significant portion of the population from easily finding suitable costumes.
