Trademark record establishes 1974 first use of the Diane von Furstenberg brand name

According to official U.S. trademark records, the "Diane von Furstenberg" mark was first used in commerce in 1974, with formal documentation citing a first-use date of March 14, 1974. This trademark filing represents the legal and commercial formalization of what had already become a cultural phenomenon: von Furstenberg's eponymous fashion label.

By this point, von Furstenberg had already launched her now-iconic wrap dress in 1973-74, a garment that would go on to sell millions of units and become one of the defining fashion items of the 1970s. The trademark registration reflects the moment her personal name transitioned from a designer credit into a protected commercial asset — a critical step for any entrepreneur seeking to build a lasting business empire.

This was significant in the broader context of the era: few women, especially those who had arrived in the fashion industry as an outsider (a European aristocrat by marriage, not formal fashion training), successfully built and legally protected a namesake global brand. Von Furstenberg's shrewd move to formalize her name as intellectual property presaged the modern era of personal-brand entrepreneurship, in which designers and personalities protect and license their own names as valuable commercial assets.

This early trademark activity underscores von Furstenberg's business acumen alongside her design talent, marking her as not just a creative force but a savvy businesswoman who understood the value of her own name decades before "personal branding" became a common concept.
