Dundas was creative director at Emilio Pucci for seven years. He had worked at Cavalli between 2002 and 2005 and called his appointment a "homecoming".
Cavalli, who founded the fashion brand with his wife in the 1970s, said the choice of Dundas "was made with the desire to evolve a style that combines glamour, tradition and innovation".
Dundas has a strong celebrity following, a fact that was stressed by Cavalli.
