The sartorial journey of the Olsen twins remains a source of endless public curiosity. But this week, Mary-Kate was spotted in a highly unusual ensemble prompting a look-back at their fashion history.

Elizabeth Olsen's Emmy Awards dress was designed by her sisters Mary-Kate and Ashley Olsen. The "WandaVision" actress wore a cream-colored dress from the Olsen's line The Row, launched in 2006.

But like many other child stars, some twins chose to leave Hollywood for good once they grew up. The Olsen twins created a fashion empire that reportedly brings in at least $100 million annually.
