A study by fashion retailer Missy Empire has revealed the most common age for successful women to launch a business is 33.

The study of 30 top celebrity female entrepreneurs, which was conducted by the eCommerce fashion brand, explored the events and factors leading to their success and revealed that 40 per cent made their millions/billions in their 30s.

More than two-thirds were self-made, and more than a half did not have a college degree.

The study showed that 43 per cent of female entrepreneurs have earned their fortunes through the fashion industry, 20 per cent in cosmetics, and 10 per cent in food and beverages.

6 per cent were in the technology sector.

7 female entrepreneurs who launched their first business in their 30s are:

  • Kristin Cavallari (30)
  • Huda Kattan (30)
  • Jessica Alba (30)
  • Oprah Winfrey (34)
  • Jessica Biel (34)
  • Kate Hudson (34)
  • Gwen Stefani (36)

Missy Empire was created by Ash and Ish Siddique in 2015 and is based in Manchester.

Based on their findings, CEO Ash said: “Female entrepreneurs are so important and they need to be talked about.

“Young people today can be inspired by these successful celebrities and know that you don’t necessarily need to have the most obvious criteria to become a Girl Boss.

“We have researched women from all walks of life, and that shows budding entrepreneurs that everybody has a chance to be successful if they work hard enough.”
