The Duke and Duchess of Cambridge were on royal duties today, attending a St Patrick's Day parade in Aldershot. The duchess was as appropriately dressed as ever, choosing an all-green ensemble that was definitely in keeping with the theme. Her coat is another high street sale bargain, the Persephone Trench from Hobbs (£195, originally £279), and the good news is it's still in stock if you'd like to get Kate's look. She switched the tie belt for a gold buckled leather number and added a hat by milliner Gina Foster, plus dark green suede court shoes and a matching clutch. Green with envy over this look? We've got plenty of ways to copy Kate below!
