Kate Middleton, Duchess of Cambridge, in Ralph Lauren

One of the charities that Princess Di was particularly supportive of was Centrepoint - a charity that helps homeless youngsters get back on their feet and find jobs and shelter. With shelters all over London, she used to take the Princes William and Harry to see how people less fortunate than themselves lived. And William in particular has grown up to be an integral part of the charity's work as their patron. Now that it is freezing cold and just before Christmas, Prince William chose this time to show his support for Centrepoint with an official engagement yesterday. And he took along his wife, Catherine. Kate Middleton, Duchess of Cambridge, wore a khaki green polo neck knitted dress by Ralph Lauren Blue Label. Nice and chic with an edge of dress down. Perfectly pitched. Of course you KNOW I am going to moan about those boots - her favourites and my worst - and I would also have left off the belt for a more modern take, but all in all, Kate looked lovely and appropriate and seemed to have a whale of a time with the youngsters.

Prince William also looked nice in his lovely blue jumper and cords - but I particularly liked his loafers. Very elegant. Unlike the moves he showed off inside... Funny. Go royals. You are doing exactly the right stuff here and looking good doing it too.
