What is Sara Blakely's net worth? Sara Blakely's net worth is $1 billion dollars. Born in Clearwater, Florida, Sara Blakely graduated from Florida State University, and paid her way through school working at Disneyworld. After selling fax machines door-to-door after graduation, she became frustrated with her pantyhose, and wondered why there were no footless pantyhose available on the market. She designed her own, moved to Atlanta to work with local manufacturers, and eventually convinced a North Carolina-based retailer to carry her line. After trademarking the hose herself, she went national, selling her hosiery directly from her home. Soon, her brand, Spanx, was available in multiple retail locations and online. Twelve years later, she is valued at $1 billion dollars. She launched the Sara Blakely Foundation to support other young female entrepreneurs, and also provided scholarship funds for an organization that supports community and personal development in South Africa. She has also appeared on multiple reality shows, including "The Rebel Billionaire" and "American Inventor".
