Which 1985 Barbie doll was designed to change from an office outfit into an evening look?

The 1985 Barbie doll designed to change from an office outfit into an evening look was Day-to-Night Barbie.

Day-to-Night Barbie turned one doll into two coordinated fashion roles. The daytime ensemble represented office dressing, while additional pieces transformed the look for evening. This idea reflected the 1980s concept of versatile wardrobe dressing, in which a professional outfit could be adapted for social occasions.

The release belongs to a long tradition of Barbie career and fashion dolls that used clothing changes to encourage role-play. Barbie could be imagined as a professional during the day and a glamorous guest after work, with the transformation communicated through garments and accessories.

Day-to-Night Barbie is sometimes confused with Working Woman or Career Girl, which represent office-focused fashion without the same day-to-evening concept. The name itself identifies the key feature: a wardrobe transition across two parts of the day.
