Which Barbie doll introduced the Day-to-Night career-fashion concept in 1985?

Day-to-Night Barbie introduced the career-fashion concept in 1985.

Day-to-Night Barbie was designed around the idea that one outfit could serve both professional and evening settings. The doll’s clothing and accessories represented a transition from workwear to a more formal night look, reflecting the fashion marketing of the mid-1980s.

The concept made Barbie’s clothing central to the story: her wardrobe showed how a character could move from an office or business setting to a social event. It also fit Mattel’s long-running practice of using Barbie’s careers to introduce contemporary clothing styles.

Collectors sometimes confuse this doll with other career Barbies because many used business clothing. Day-to-Night Barbie is specifically identified by the day-to-evening wardrobe concept, rather than simply by having a professional occupation.
