Fürstenberg wrote two top selling books: The Power Look (1978), a guide to fashion and good taste, and The Power Look at Home: Decorating for Men (1980), a book on home furnishings. He opened an interior design firm in 1981. In 1991, he exhibited at Alta Moda days in Rome.

Fürstenberg began independent work as a fashion designer in 1977, designing clothes for plus-size women, and later expanding to full fashion and product licensing, with ready-to-wear, fragrance, and made to measure lines based in Rome. Next von Furstenberg designed ready-made clothing for the masses, and an off-the-peg (ready-to-wear) line of fashion.

In 1969, he married fashion designer Diane Halfin, with whom he had two children, Prince Alexandre Egon (b. 25 January 1970) and Princess Tatiana Desirée (b. 16 February 1971). The couple separated in 1973 and divorced in 1983. The same year, he married Lynn Marshall (born c. 1950), an American from Mississippi who was the co-owner of a flower shop; the couple remained childless. Between his marriages, Egon also had a male partner; he was frank about his bisexuality and the openness of his first marriage.
