Kate Middleton and Prince William attended the annual Commonwealth Day Service.

This was Kate's first public appearance since becoming Princess of Wales.

Kate wore a navy Erdem peplum jacket and skirt with a white floral embroidered print.

She accessorized with sapphire and diamond drop earrings that previously belonged to Princess Diana.

She also wore Queen Alexandra’s Three Feathers Brooch.

Kate tucked her hair into a braided low bun and combined her rosy cheeks and pink lips with a subtle smokey eye.

William wore a navy suit and blue tie.

The event took place at Westminster Abbey, where they exchanged vows on their wedding day.

The couple was welcomed by members of the Ngāti Rānana London Māori Club.
