The deep royal blue hue enhanced Kate’s bronzed glow.
The double-breasted tuxedo style dress, £139 from Reiss, with full-length sleeves, featured a matching dark blue belt with a gold buckle.
Kate wore the dress eight years ago in 2012 to give her first public speech, bringing the look full circle to a huge announcement in her biggest project to date.
Kate’s makeup was neutral and subtle, with brown eyeshadow and a little eye-liner to define the Duchess’s eyes.
Her eyebrows defined and she wore a peachy pink on the apples of her cheeks and on her lips.
Kate’s hair was beautifully curled, bouncy and shiny.
The look appeared crafted to draw attention to Kate’s pendant necklace, a shining gold disk.
