Kate is Pretty in Plum for SportsAid...

Today the Duchess attended an event on behalf of SportsAid. She arrived just before 3pm to visit Olympic hopefuls.

The Duchess was joined at the SportsAid event by swimmer Keri-anne Payne, who won silver at the 2012 Olympics and is also a two-time World 10km Open Water champion, and wheelchair athlete David Weir CBE.

Today the Duchess returned to a tried and tested British label - Goat. The Duchess first wore Goat last year when she visited the headquarters of Child Bereavement UK with Prince William and then again in July this year when she attended an M-PACT event in London.

Today Kate chose the Vreeland Dress in Iris. It is currently available for £450 on the Goat website.

The Duchess chose to keep her look casual today and teamed the dress with opaque black tights and flat boots. The pictures aren't very clear but it is looks like they are new boots from Stuart Weitzman - the Half n Half Stretch Rider Boots which retail for £455 at Russell & Bromley. She also added her Stuart Weitzman Muse clutch that she took to Wales last week. It is still available at Russell & Bromley for £255.

The Duchess repeated her diamond and sapphire drop earrings too.

Copy Kate
A shirt dress in a dark winter colour is perfect for the colder months. Like Kate, team it with opaque tights and knee-high black boots. Hawes and Curtis have lots of shirt dresses in the sale currently, however for one most similar to Kate's choose the French Navy Shirt Dress. It has similar features, such as the belted waist and 3/4 sleeves. It is currently on sale from £99 to £49.50. Principles by Ben de Lisi have a gorgeous pair of flat knee-high black suede boots in the sale for £48.75 (they were originally £65). They will last you the whole of winter and look amazing! I really like the buckle detail around the ankle. And don't forget your opaque tights, for me the thicker the better in winter. John Lewis Polar Fleece Tights will ensure your legs stay warm in the cold weather.

I liked the Duchess's casual ensemble today and I hope you like my 'copy Kate' version. I will update this post as more pictures from the event emerge!
