Worn by The Queen for the Investiture of Prince Charles as Prince of Wales at Caernarfon Castle, 1 July 1969, this ensemble of pale primrose yellow comprises a silk crepe long-sleeved coat and matching tunic, both applied with pearl and bugle bead embroidery. The striking hat of the same pale primrose yellow silk consists of a crown entirely embroidered with pearls and bugle beads. To the crown is attached a panel of silk with lines of embroidery which covers the back of the head to the nape of the neck. The hat appears to have been inspired by Tudor prototypes and was a style repeated on several occasions in different colours and materials.
