As far as déjà vu goes, it’s pretty spectacular.

Duchess of Cambridge Kate Middleton and her husband Prince William have just arrived at Westminster Abbey to mark the 60th anniversary of the Queen's Coronation – their first public appearance together at the iconic landmark since they were married there just over two years ago.

And what a difference two years make.

With just one month to go until she’s due to give birth to the couple’s first child, Kate looked relaxed and happy in a peach-colored summer dress by Jenny Packham and matching lightweight coat, accessorised with a veiled hat by one of her favourite milliners, Jane Taylor.

Plus, today’s formal service has another star of note in attendance.

The iconic St Edward's Crown will rest on the High Altar during the ceremony, marking the first time it has left the Tower of London since it was used to crown the Queen during the 1953 coronation.
