The Prince and Princess of Wales attended the annual Commonwealth Service at Westminster Abbey.

Kate usually wears coat dresses from designers like Catherine Walker and Alexander McQueen for formal events.

This time, she wore a pre-fall Erdem look, which won't be available until August 2023.

Erdem is a popular choice for Kate because his designs often have historical and royal inspiration.

Kate's navy blue jacquard-print skirt suit had an elegant silhouette with a pleated peplum and flared skirt.

The pre-fall collection was inspired by Victorian house wallpapers and upholsteries.

Kate accessorized with a navy blue hat, navy blue suede court shoes, and matching gloves.

She wore sapphire and diamond drop earrings that belonged to Princess Diana and a Prince of Wales feathers brooch.
