What was the name of the blouse from Givenchy's debut 1952 collection?

The blouse from Givenchy’s debut 1952 collection was the Bettina blouse.

Hubert de Givenchy opened his Paris fashion house in 1952 with a collection called Les Séparables. Its fresh, youthful designs included a white blouse with dramatic puffed sleeves and a distinctive high collar. The piece was named for Bettina Graziani, the celebrated French model who helped promote the new house and worked closely with Givenchy.

The blouse quickly became the signature image of Givenchy’s first collection. Artist René Gruau helped make it famous through an illustration, while the collection’s use of relatively simple cotton helped distinguish Givenchy from more formal couture houses. The design’s name is sometimes confused with Audrey Hepburn because Hepburn later became Givenchy’s most famous muse, but the Bettina blouse predates that relationship.

Graziani was already a major fashion figure in the 1940s and 1950s. Her association with Givenchy helped give the young designer immediate visibility, making the blouse both a garment and an early piece of fashion-brand storytelling.
