The queen paid tribute to Meghan Markle and Prince Harry while visiting Kate Middleton's garden

Queen Elizabeth paid a subtle tribute to her grandson Prince Harry's wedding anniversary on Monday, May 20th while attending the Chelsea Flower Show. The royal matriarch, who recently became a grandmother for the eighth time, wore the exact same outfit as she did to Meghan and Harry's wedding ceremony at St. George's Chapel in Windsor.

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.”

The outing occurred one day after the Duke and Duchess of Sussex's anniversary, who got married on May 19, 2018. While we probably won't see Meghan for a while, as she's on maternity leave, Harry has returned to work and was already spotted wearing some hilarious new dad gear.
