It's been a week of colour - we had Think Pink. Then purple for World Lupus Day. Then this wonderful green gown of Michelle Obama just knocked me off my perch. It could have come straight out of a Renaissance portrait or Stuart panel. Those flowers are three-dimensional raised work and are simply fabulous. Step back Anna Wintour (though much respect) and step back Cecil Beaton debutantes - let's hear it for the First Lady!
