Kate Middleton and Prince William attended a Holocaust Memorial Day Commemorative Ceremony at Westminster Central Hall tonight. The Duchess of Cambridge wore a number of pieces fashion fans will recognise.

The mother-of-three wore a grey coat dress from favourite designer Catherine Walker.

She has previously worn the garment to team up with the Queen for a joint outing in October last year.

Tonight she wore the dress with the Cavolfiore Pearl Studs from Cassandra Goad, worn for Prince Louis’ christening.

With a shop in Sloane Square, the jewellers website states: “Her jewellery is worn by Lord Mayors, countesses, princesses.”

The earrings are available to order from £4,360. They are constructed of 18ct yellow gold and set with seven pearls set with diamonds (0.3cts).

Kate’s clutch bag was the Celeste Velvet Clutch by Jimmy Choo.

Ahead of Holocaust Memorial Day the Duchess shot a number of photographs of survivors of the atrocity.

Kensington Palace said in a statement: “The Duchess of Cambridge has taken two photographs of Holocaust survivors and their grandchildren as part of a project by @HMD_UK, @JewishNewsUK and @The_RPS to mark the 75 years since the end of the Holocaust.

“The project aims to honour the victims of the Holocaust and to celebrate the lives that survivors have built in the UK, whilst also reminding everyone of their own responsibility to remember and help to share the stories of those who endured Nazi persecution.”

Kate shot the portraits of Yvonne Bernstein and Steven Frank at Kensington Palace, next to a window facing east. This is so that they were facing the direction of Jerusalem.

The Duchess said: “It is vital that their memories are preserved and passed on to future generations, so that what they went through will never be forgotten.”

Today is the 75th anniversary of the end of Auschwitz, just one of the many concentration camps where victims of the Holocaust, including Jewish people, Slavic people, members of the LGBT community and those with disabilities were murdered.

Twitter users poured praise on the Duchess.

One said of the ensemble: “Beautiful, elegant, happy. A dress, already seen but the right one for today’s tributes.”
