Fendi began in 1918 when Adele Casagrande opened a leather and fur shop in Via del Plebiscito in central Rome. When Adele married Edoardo Fendi in 1925, they made a decision to change the name to Fendi. The business prospered, and a new shop was opened in Via Piave in 1932. By 1946 Paola, 15, the eldest of the couple's five daughters, went to work for the firm, followed by her sisters Carla, Anna, Franca, and Alda.

In 1965 a marriage between the Fendis and German designer Karl Lagerfeld was sealed, and it proved to be fortuitous for both. Lagerfeld immediately created the inverted FF logo that joined the growing list of international status symbols, and then set about, aided and abetted by the sisters, to revolutionize the treatment of fur and other clothing.

Marvin Traub, president of Bloomingdale's, discovered Fendi's leather goods and introduced them to the United States. Other outlets soon followed, and today Fendi is largely represented through high-end department stores.

In 1969 Fendi presented its first ready-to-wear fur collection at Palazzo Pitti in Florence, bringing continuously evolving techniques and imaginative designs to lower-priced furs without sacrificing quality. When the sisters could not find the fabric clothes they wanted to show under the furs their ready-to-wear line was born, again to great success.

The company's accessories are now found on the arm of many stars and signature bags such as the Spy, buckled B-bag, and embellished bucket bag are often in high demand sometimes creating long waiting lists.
