Kate Middleton knows the eyes of the world are on us for London 2012 and she and Prince William are going to be at every Olympic event possible.
For a visit to the National Portrait Gallery last week, Kate chose a patriotic royal blue dress designed by Stella McCartney - who created Team GB's official kit - accessorised with a ringed necklace from Cartier which cost £49,000.
Don't tell Prince Charles, who pays his daughter-in-law's work wardrobe, but Kate could've found a similar necklace by Diamonique by Andrea McClean at QVC for £53.25, which would've saved £48,946.75!
