Kate Middleton and Prince William made an appearance with the Irish Guards on St. Patrick's Day.

This was Kate's first appearance as the colonel of the regiment, taking over the role from William.

Body language expert Judi James noticed that Kate gave William a cold, hard stare as a power play signal.

Kate's body language was military rather than royal, showing how seriously she is taking her new role.

William responded to her stare with a puckered-looking smile to suggest pride and respect for Kate.

Body language expert Darren Stanton believes Kate wore superhero colors to assert her control over William and the other guests.

Kate tends to choose bold colors when she wants to be perceived as powerful.

During her first appearance as Colonel of the regiment, Kate plainly wanted to make her position known to the crowds.

The author is in support of Kate taking over William's role and giving him side-eyes.
