My Wardrobe have just taken delivery of some pieces from Mary-Kate and Ashley Olsen's 'Elizabeth and James' collection, the slightly (and I do say slightly) more affordable sister to their high-fashion 'The Row' range. And as much as it pains me to say it, the twins really do seem to know what they're doing, with a particularly beautiful set of jackets with interesting shapes and cuts. The double-breasted blazer is £314, as is the slouchy glossy black jacket. For full Olsen style obviously these need to be teamed with artfully messy waved hair, lots of black eyeliner and a floor-skimming maxi dress and killer heels.
