Petra Ecclestone
$500 Million

Petra Ecclestone is the second daughter of Slavica and Bernie Ecclestone. She was born into riches, making it easy for her to translate it into her own niche. She created the menswear label FORM at age 19 and has continued to design and manufacture clothing. She resides in the largest home in Los Angeles, which she has since listed for sale for as high as $200 million.
