During their trip to the United States, Prince William and Kate Middleton demonstrate their love and respect for one another.

According to Judi James, a body language expert, the couple's arrival poses make a big impression and sell their charisma.

William and Kate appear to be a happy couple because they wear matching simple, elegant suits.

Their subliminal mirroring rituals and visual symmetry indicate a close couple.

They don't need to hold hands or hug to express their feelings.

They make eye contact as they walk side by side, resulting in the "look of love."

Kate polishes her earrings and observes her husband as he converses with their hosts.

With the earring in his eye-line, William looks proudly and adoringly at his wife as she speaks.

Overall, the body language of the couple conveys a sense of respect, love, and a strong bond.
