The concept refers to coordinated or thematically linked outfits chosen by three female siblings for the Halloween holiday. These selections often reflect shared interests, popular culture references, or a desired aesthetic unity. An example could be three individuals dressing as characters from a specific film or book, each portraying a distinct role within that fictional universe.
The practice fosters familial bonding and collaborative creativity. Participating individuals experience the benefits of joint decision-making and the expression of a unified identity. Historically, such coordinated costuming may stem from traditions of group celebrations and a desire for visual harmony within social gatherings. The concept can also strengthen relationships among the involved individuals.
