The Duchess chose to rewear her Missoni 'Long Snake Stitch Coat' to today's service. This was worn last year to the Battle of the Somme commemorations in France with a black pillbox hat.
It is described: "Silver metallic threads shimmer within the monochromatic hues defining a textured A-line coat that's visually shaped with an angled zigzag pattern."
Kate paired the £2,900/$3,600 single-breasted coat with her black Sylvia Fletcher for Lock & Co. cocktail that which has been worn a couple of times in the past.
She carried a new clutch; this one is the Beulah London Aspinal Blue Heart Clutch in black croc available for £229/$285. A collaboration between the two brands, this clutch's interior is lined with Beulah London's iconic blue heart print while Aspinal of London's signature shield lock clasp is visible from the outside.
Kate had on her Gianvito Rossi 'Gianvito 105 Suede Pumps' which are available at My Theresa for £540/$675.
The beautiful silver and pearl earrings are borrowed from the Queen; she most notably wore them during her Silver Jubilee in the '70's. Kate first wore these in Canada last year.
It was another appropriate look for the Duchess. She knows exactly when to play it down and keep the attention on the event itself through wearing repeat outfits.
