Kate Middleton recycles hat from her first joint engagement with the Queen

Sabrina Carder

On Tuesday morning the Duchess of Cambridge joined The Queen for their first joint engagement in seven years.

The royals arrived at Kings College to open the newly renovated Bush House, the latest education and learning facilities on the Strand Campus. The occasion being the first time the royal pair have carried out a solo engagement together, as their first joint appearance in Leicester to commemorate the Queen’s Diamond Jubilee tour in March 2012 was also accompanied by Prince Philip.

Echoing a similar aesthetic to their first outing, the Queen once again stood out in pink, this time swapping hues of magenta for a dusty rose.

Kate's outfit was equally as nostalgic, as the 37-year-old recycled the same pillbox hat with felt floral detail by Lock & Co that she wore the first time around.

Known for her love of recycling her wardrobe, the mum-of-three has been seen in the millinery numerous times since its debut in 2012, donning it again to the Remembrance Sunday in 2013 and to the St Patrick's Day Parade that same year.

Kate's ensemble for the rare occasion was very different to the bottle green two-set by the now failing high street store L.K Bennett that she wore for their first engagement.

Looking every inch the sophisticated royal, Kate opted for a tailored grey coat dress with matching belt by Catherine Walker & Co, a London designer much loved by Kate's late mother-in-law, Princess Diana.
