At Wimbledon in 2008, Kate donned a white Issa "Lucky" dress, paired with a black cardigan. Three years later, sis Pippa wore the same frock, but with a red purse and matching flats while out in London.

LADIES IN RED
For a friend's wedding last September, Kate dressed up a Collette Dinnigan red lace dress with a festive fascinator and black pumps; her mother wore the lace number two years earlier for the Royal Academy's Summer Exhibition in 2009.

While lunching in London with stepmother-in-law Camilla in February 2011, Kate topped her black-and-tan dress with this beige jersey knit jacket from Whistles. Fast forward to three months later, Pippa wore it on top of a patterned frock while running errands in the same city.

To christen a lifeboat in Anglesey, Wales, last February, Kate chose a neutral Katherine Hooker coat – the same one Pippa then wore to a friend's December 2011 nuptials in Suffolk.
