Vera Wang was a late bloomer, compared to the rest of the ladies on this list. It wasn’t until she designed her own wedding dress at the age of 40 that she decided to start her own fashion label. Luckily, Wang had all the right contacts having worked at Vogue magazine to make her brand a success. She has since expanded her company and now designs everything from jewellery to home and kitchen wear, as well as clothes, shoes and accessories.
