Kate Middleton at the 2012 Summer Olympics

Kate doesn't have to wear designer dresses all the time! The Duchess of Cambridge wears an affordable discount dress right off the sale rack of Hobbs, a mid-priced British label. The Duchess played soccer and ping-pong at a pre-Olympics event for the launch of a new sports project in London. The '50s-inspired frock costs only $60 but is unfortunately already sold out in stores.
