Ivy Ralph was born in 1928 in Manchester, Jamaica, and trained at the Fashion Institute of Technology in New York before founding her own atelier, the House of Ivy, in Jamaica.
In the early 1970s, Ralph set out to design an alternative to the European jacket-and-tie suit, which she considered impractical for Jamaica's tropical climate — describing it as an idea she had held 'since childhood.' The result was the Kariba, or Kareeba, suit: an open-necked, short-sleeved shirt worn untucked over matching trousers, designed for comfort and airflow without sacrificing formality.
The suit gained national prominence when Jamaican Prime Minister Michael Manley began wearing it publicly, and in 1972, following the People's National Party's election victory, Jamaica's Parliament formally recognised the Kariba as appropriate attire for official government functions. Other Caribbean and African leaders soon adopted the style, including Barbadian Prime Minister Errol Barrow, Guyanese President Forbes Burnham, and Tanzanian President Julius Nyerere, turning the suit into a broader symbol of post-colonial identity across the region and continent. At the height of its popularity, custom-fitted Karibas sold for $65 to $70, and Ralph's designs were exported to department stores including Saks Fifth Avenue.
Ralph was awarded Jamaica's Order of Distinction in 1999 for her outstanding contribution to the promotion of fashion. In 2025, decades after the suit's creation, an original Kariba designed by Ralph was acquired by the Metropolitan Museum of Art in New York, formally entering the collection of one of the world's most prominent fashion archives. Her daughter, Sheryl Lee Ralph, is an Emmy Award-winning actress; her son Michael Ralph is a voice and film actor.

- Practical design can carry political weight. Ralph's suit began as a solution to tropical discomfort and became a formal, government-recognised symbol of post-colonial identity.
- Recognition can arrive decades after the work. The Met's acquisition of her design came more than fifty years after she first created it.
