The queen donned the elegant lime green coat and floral dress (minus her signature hat), while supporting Kate Middleton and her most recent project, the "Back to Nature Garden." 

The Duke and Duchess of Cambridge gave the queen a personal tour of the garden that the duchess created with landscape architects for the show to demonstrate the benefits nature can provide for mental health. 

“I really feel that nature and being interactive outdoors has huge benefits on our physical and mental wellbeing, particularly for young children," the royal said.

She continued, “I really hope that this woodland that we have created really inspires families, kids and communities to get outside, enjoy nature and the outdoors, and spend quality time together.”
