The aforementioned phrase refers to coordinated Halloween attire for two people, where one member of the pair is expecting a child. These costumes often incorporate the pregnant partner’s baby bump into the overall design. For example, one individual might dress as a baker, while the other portrays a literal “bun in the oven.”
Choosing such an ensemble can be a fun and creative way to celebrate the impending arrival of a new family member. It provides an opportunity for lightheartedness during a significant life event and allows the couple to share their joy with others. Historically, costumes during holidays like Halloween have been a means of communal expression, and this particular theme continues that tradition with a modern, celebratory twist.
