I'm no body language expert, but even I could tell that the Duke and Duchess of Cambridge looked very happy and in breath when they visited Glasgow, Scotland.

Thankfully, Darren Stanton, an actual body language expert, agrees with me: this engagement really shows "the strength of their relationship," he says.

"Their confidence in each other and their relationship is evident in how synchronized they were when they were out together," Stanton tells Marie Claire on behalf of Slingo (open in new tab)." You will notice that Kate and Will often match and mirror each other's body positions and gestures, such as standing with their hands together in front of them and waving one hand at the crowd." This is indicative of the deep connection they share and the strength of their relationship.

The royal couple headed to Scotland to talk about the various initiatives surrounding early childhood and mental health, two of the causes closest to their hearts.

Proving once again that monochrome is the new color blocking (and taking a cue from the Queen's own fashion book), Kate Middleton wore one of her favorite designers, Catherine Walker's navy blue calf-length coat (similar here design), a cornflower blue blouse by Cefinn (opens in new tab) (this particular color is sold out, but can be pre-ordered), navy tailored pants, and navy pointed pumps.

She wore the same Annoushka pearl earrings (opens in new tab) that she has worn for years (perhaps a gift from a loved one), a black belt, and a Parisian brand that she also carried at her previous engagement ceremony, in memory of the victims of the Manchester attacks She accessorized with a small blue handbag (opens in new tab) from Polène.

The Cambridges first visited a "Roots of Empathy" session at an elementary school. They wrote on Instagram, "It's a very progressive approach to guiding children to understand the needs and feelings of babies."

There, both royals were completely in their element, but especially the Duchess. Stanton said, "Kate's maternal instincts were on full display throughout the engagement, whether it was when she read a storybook to the baby, stopped to interact with the young children, or knelt down to make sure they were at the same eye level."

He adds, "Eager to do things their own way, Kate sits kneeling with the children alongside William. We have never seen the Queen pose like this or interact so closely with the public.

The Cambridges then visited the University of Glasgow to talk about student mental health, especially during exam season. They also visited the Wheatley Group to learn about the challenges of homelessness in the city and Scotland in general.

"The support provided by the University of Glasgow and the understanding and empathy of the students gave us a real insight and highlighted the importance and value of talking about mental health, especially during this #MentalHealthAwarenessWeek," they wrote on Instagram.
