But, expert Judi James told Daily Mail that the lack of eye contact between William and Harry told the real story.
Of Kate and Meghan, James says: "It reminds me of political body language. The kind of thing politicians do when they're walking with other heads of state and want to show some signs of rapport or unity."
According to reports, prior to Christmas day the Queen and Prince Charles made it clear that any rift between the two duchesses must be kept out of the public eye as they arrived together at the St Mary Magdalene Church.
Their body language spoke volumes about how the two women really feel, says James.
"They're walking in step, and there's enough mirroring to suggest like mindedness too. Kate has her left hand raised at the same time as Meghan - they're both gesticulating in an over-congruent way to show they're having a conversation.
"It looks performed, they're possibly trying a bit too hard."
