His business partner Giancarlo Giammetti might criticise Mr Valentino for his rather liberal application of self-tanner, but we say who better to give fashion advice to the women of the world than Mr Valentino, the man who knows how to make a stand-out, uber-flattering dress? ‘Not too much. Don't do too much,' he told Oprah on US television yesterday – watch it here. ‘Try to have a nice pair of shoes, a nice bag, a beautiful blouse, a nice cut pair of trousers.' And it's not just women for whom Valentino has strict fashion rules. According to the director of his documentary, The Last Emperor, Valentino wasn't too happy about Matt Tyrnauer wearing a blue shirt and jeans every day of the shoot – or when he tried to appease him by dressing up. ‘Valentino said, "A gentleman never wears a white shirt before six in the evening." He likes to rib you. He plays the role of imperious icon, and he plays it well. This is someone who doesn't leave the house unless the outfit is perfect, the appearance is perfect.'
