  • Age: 31, 33
  • Title: Creative Director & CEO
  • Company: Ralph & Russo

In six years the bespoke clothing label founded by these two Aussies has attracted a clientele that includes Angelina Jolie and royals the world over. R&R's handmade pieces fetch up to $500,000 and range from baby garments to Beyoncé's crystal-studded stage wear. Nimbler and more exclusive than the big houses, R&R gets gowns to the rich and famous faster (four weeks instead of six months) and with a white-glove touch (Cartier on site; chauffeured rides in a Rolls-Royce). Ralph, a fourth-generation couturier who sold dresses to Sydney's socialites as a teen, handles the fashion; Russo, the finances—the company is growing 400% a year.
