Kate Middleton and Prince William always travel with this key item when away

Prince George and Princess Charlotte also have a miniature version of the suitcase.

It was estimated the four suitcases, as well as a smaller vanity case, spotted doing the Cambridges’ Poland tour, cost as much as £5,000 for the entire luggage collection.

Princess Diana also used the iconic brand for her honeymoon with Prince Charles.

Prince Harry has not been spotted with the iconic British brand suitcase, however.
