Kate Middleton in Erdem at Trooping the Colour

It was another frock rocking occasion for the Duchess of Cambridge this weekend. Catherine attended the Trooping the Colour for the official celebrations of the Queen's birthday. For a change she didn't opt to recycle one of her old favourites, but rather pop on a piece from one of her favourite designers, Erdem.

For this latest public appearance, Kate wore a silver-grey bespoke Erdem dress. Embroidered with floral designs, the dress folded at the neckline and included his trademark three-quarter sleeves and knee-grazing hem. With her hair let loose down around her shoulders, the Duchess enhanced the elegance of her look with a matching light grey fascinator by one of her most cherished milliners, Jane Corbett. A hard-cased pale grey clutch and Links of London drop earrings helped to finish off her ensemble in the most classiest of ways.

Catherine arrived at the ceremony with the Duchess of Cornwall in a pastel blue ensemble and Prince Harry in his regal military uniform. The group travelled to the Horseguards Parade by horse-drawn carriage. The Queen did a spot of recycling herself by choosing to wear a lemon yellow Angela Kelly number which is the same outfit she wore to the royal wedding of Prince William and Kate Middleton in June last year. So you see, thriftiness runs in the family.
