Kate Middleton appeared to pay a touching tribute to her late mother-in-law as she launched her new book.
In a new photo released to mark the pending launch of the book the Duchess of Cambridge her choice of outfit looked similar to one Princess Diana wore in 1981.
The look has echoes of the style regularly worn by Lady Diana, who often wore blouses and shirts with a similar pie-crust style collar.
Kate's Hold Still project was launched last year and invited people of all ages from across the UK to submit a photographic portrait which they had taken during the first lockdown.
From over 31,000 images submitted, 100 final portraits were selected and shown in a digital exhibition before being displayed across the UK.

The book, named Hold Still: A Portrait of Our Nation in 2020, will raise cash for mental health charity Mind and the National Portrait Gallery.
Mum-of-three Kate wanted to create a lasting legacy of how the country has collectively and individually battled through lockdown, celebrating the NHS and recognising how everyday people have coped during the pandemic.
In the introduction, Kate, 39, wrote: "When we look back at the Covid-19 pandemic in decades to come, we will think of the challenges we all faced – the loved ones we lost, the extended isolation from our families and friends and the strain placed on our key workers.
"But we will also remember the positives: the incredible acts of kindness, the helpers and heroes who emerged from all walks of life, and how together we adapted to a new normal.


“Through Hold Still, I wanted to use the power of photography to create a lasting record of what we were all experiencing – to capture individuals’ stories and document significant moments for families and communities as we lived through the pandemic.”
As well as showcasing the final 100 images and the stories that accompany each of them, the book will look back at highlights from the community exhibition which took the portraits to billboards and outdoor poster sites in 80 towns, cities and areas in October 2020.
