Catherine Duchess of Cambridge wore Alexander McQueen Gown during official dinner hosted by Malaysia Head of State Sultan Abdul Halim at Istana Negara. Not only do the gown wow!. More than anything though, I was struck by the gold embroidery on the gown. The glittering gold embroidery actually was done in the shape of a hibiscus the official flower of Malaysia. It's true when they said, it's the little details that are vital.
