The Duchess of Cambridge made a private visit to Evelina London children's hospital on Friday to meet patients, families and staff unable to join in the Platinum Jubilee celebrations this weekend.
Evelina London tweeted photos of their royal patron following the surprise visit.
It appears the Duchess wore her red L.K.Bennett 'Cayla' Dress. Unfortunately, no other outfit details are identifiable.
