THE OLSEN TWINS | $100 MILLION

Out of all former Hollywood child stars, Mary-Kate and Ashley Olsen are among the ones who became successful in transitioning from acting to bonafide business moguls. Before that, they were renowned Hollywood sweethearts who started appearing in television before they were even a year old and even shared Michelle’s role on the ABC sitcom Full House. Later, they launched their own company named Dualstar and released countless TV movies featuring both of them.

However, as years went by, the twins quickly grew tired of their entertainment career and embraced their passion for fashion instead. Not long after realizing that, Mary-Kate and Ashley splurged their investment money into their fashion brands, The Row and Elizabeth and James. They also established affordable fashion lines such as Olsenboye and StyleMint. Forbes even named them two of the richest women in Hollywood at just 20 years old. In 2007, they had an estimated joint net worth of $100 million.
