On Friday, designer Zac Posen announced the immediate closing of his eponymous fashion label, which launched in 2001.

In a press statement, the former "Project Runway" judge said he was "deeply saddened that the journey of nearly 20 years has come to an end" but that he was "grateful to the team who lent their incomparable talent and commitment along the way."

"The management team … worked extremely hard to navigate the increasingly challenging fashion and retail landscape," he said in the statement. "We are disappointed that these efforts have not been successful."

Over the years, Posen became known for his glamourous ball gowns and curve-hugging designs.

Some of his most famous looks include the pink satin dress he designed for Rihanna at the singer's 2014 Diamond Ball, the light-up Cinderella gown he created for Claire Danes at the 2016 Met Gala, and the dress Princess Eugenie of York wore to her wedding reception. But those are far from the only iconic moments the designer has had.

A spokesperson for Zac Posen didn't immediately respond to a request for comment from Business Insider.
