Royal Tour Day 10: Duchess, a ray of sunshine in Roksanda Ilincic for first day in Australia

This afternoon, the royal trio emerged from their flight from Wellington to commence the Australian leg of their royal tour in Sydney.

Kate wore a sunshine yellow sheath dress by London-based designer Roksanda Ilincic. No doubt the Duchess selected this colour to reflect the gold of Australia's national colours - green and gold.  The dress is a modified version of the Roksanda Ilincic 'Ryedale' wool-crepe dress.  The off-the-rack dress from the spring/summer 2014 collection features bell sleeves and has an exposed back zipper. It currently retails for £941.

Kate's bespoke version has the block colours reversed, with the yellow being the dominant hue.  The sleeves have also been fitted and the neckline modified from round to square.
