Keira Knightley
In 2014, actress Keira Knightley told Glamour magazine that she tries to live off a $50,000-a-year salary, even though she makes millions from her film roles. “I think living an expensive lifestyle means you can’t hang out with people who don’t live that lifestyle,” Knightley said. The star also wore a recycled dress at her 2013 wedding to rocker James Righton in a move that could be considered more practical than cheap.
