For her visit to Greece, Angela Merkel's soft green jacket should have been just the right colour choice to convey a sense of calm. That is, if it wasn't the very same one the German chancellor wore to celebrate Germany's victory over Greece during Euro 2012. But with fashion not coming to her as naturally as economics, Merkel has got her formula and she's sticking with it. Her signature look comprises three-button blazers, often from German designer Bettina Schoenbach, in a huge range of colours. Dutch graphic designer Noortje van Eekelen even created a Pantone chart of the look for her website The Spectacle of Tragedy. From black to beige to a very on-trend purple, it runs to an impressive 90 shades. That's one for every situation Europe's most powerful woman might find herself in.
