Haven't we seen Kate's pageant dress somewhere before? Kim Kardashian and Tulisa have BOTH worn Duchess of Cambridge's Alexander McQueen dress (though theirs were a lot racier)

The Duchess of Cambridge is never afraid to wear something that might not be bang up to the minute.
The majority of the clothes she wears are classic pieces that might be from one or two, even three seasons ago. But they are united in the fact that they suit Kate to a tee.
So it is no surprise that Kate chose a piece from Alexander McQueen's 2011 collection for her appearance on board the royal barge in the Queen's Jubilee pageant today.
What is surprising though, is that the Duchess seemed to have taken style inspiration from two most unlikely celebrities.

De-ja vu: The Duchess of Cambridge's Alexander McQueen dress has previously been worn in sleeveless form by Kim Kardashian, centre, and Tulisa Contostavlos, right, though 5ft 10in Kate had her version made longer to suit the occasion
