Plein's transition to fashion occurred in 2004, when he began using leather scraps from his furniture to create accessories and bags. These accessories were highly successful, leading him to launch his first clothing collection. Plein's fashion is characterized by an opulent and aggressive style, often decorated with skulls, studs, crystals, and bold motifs. This distinctive aesthetic quickly gained followers among celebrities and fashion enthusiasts.

The Philipp Plein brand is also known for its spectacular and lavish runway shows, which often include musical performances and elaborate sets. These events have helped consolidate the brand as a symbol of extreme luxury and spectacle. In 2008, Plein opened his first mono-brand store in Monte Carlo, followed by numerous other locations worldwide, from Milan to New York.

Philipp Plein has continued to expand his luxury empire with the launch of additional lines such as Plein Sport, dedicated to high-end sportswear, and Billionaire, a luxury menswear brand acquired in 2016. Despite some controversies and criticism for his provocative style and eccentric personality, Plein has proven to be a skilled entrepreneur, building a brand that is synonymous with unrestrained luxury and innovation in the fashion world.
