The Olsens' 17 Best Quotes on How to Build a Multimillion-Dollar Brand

For years, we’ve idolized the twin tycoons’ inimitable style, but Mary-Kate and Ashley Olsen are so much more than street style stars. The business-savvy beauties have been building their empire since they founded their first company, Dualstar, at just 6 years old. From fashion to fragrance, the designers now run a multimillion-dollar empire with luxury clothing lines Elizabeth and James and The Row, which was recently crowned the Council of Fashion Designers of America womenswear designer of the year.

Gone are the kitschy twinsets; in their place are two respected designers and talented businesswomen who garnered $12 million in annual sales for The Row after just four years. You only have to see the brand’s stunning West Hollywood flagship (and their equally as stylish Elizabeth and James store) to see why. Clearly, they’re doing something right. Read on for some key branding insights we gleaned from the successful sister act, and be sure to click on the quotes to read the full interview.
