It was an emotional visit for the Duchess of Cambridge, as she visited research facilities at Imperial College London, learning about the work being done to prevent miscarriages and stillbirths. 

The mum-of-three has been busy the past few weeks keeping up with engagements, but there's no doubt this one will have struck a particular cord as she toured the Institute of Reproductive and Development Biology.

She met with staff from Tommy's, a UK charity that is working to reduce rates of miscarriage, stillbirth and premature birth, to mark Baby Loss Awareness Week in the UK.

Middleton also heard how the research facility is running Covid-19 trials to better understand how the virus affects pregnant women and their babies. Donning a white lab coat, Kate peered through microscopes at samples while she chatted with the staff. 

Kate also spoke to some families who have experienced miscarriage or stillbirth, including Clare Worgan who spent three days in hospital after her daughter was stillborn. "We spent those three days cramming in a lifetime's worth of memories", she told the Duchess. 

"When we went home our lives had been turned upside down. We had been devastated." Worgan then went on to train as a midwife.

Kate was moved by Worgan's story, saying, "It's so brave of you to be able to talk so openly. A lot of the research, a lot of the support for organisations, is being driven by parents who have been through this experience, and want to help others. It is so inspirational".

For the occasion, Kate dressed in a more muted outfit, but it was no less elegant. She rewore her stunning navy blue Emilia Wickstead dress, which she had worn last November to launch the National Emergencies Trust. 

The 'Kate' dress features a slim fitted bodice, long sleeves, a high neckline and a full A-line skirt. The Duchess has worn the style in multiple colours over the years, including an olive green and a lilac shade.

While last time she wore the dress she paired it with a matching navy buckled belt, this time she wore a crocodile-patterned belt accented with a metal buckle. She finished her look with a pair of navy suede pointed toe court heels by Prada. 

Of course, she added her Amaia Kids facemask in "blue pepper", a sweet blue floral print, and her Alia Hoop Earrings by Spells of Love, a striking pair of geometric squared-bottomed gold hoops. As always, Kate wore her hair in a full bouncy blow dry, with her makeup kept minimal and fresh.
