When the model, television cost and design diva Alexa Chung introduced a new fashion line in spring, no one knew who her backer was. In fact, she explicitly refused to reveal the name. In the fashion industry, secrets are rarely kept and soon everyone came to know about Peter Dubens, the managing partner and co-founder of Oakley Capital Private Equity who was the man behind the brand. A successful investor and entrepreneur, Dubens has a finger in every pie. Being a very private man, he rarely finds a mention in the media.
