Considering how irredeemably off-trend skirts were last winter - apart, of course, from the pencil skirt which has become a wardrobe classic - it is astonishing (or would be anywhere apart from the capricious world of fashion) that this year a skirt is one of the most sought-after garments.
This is partly down to the novelty factor. We have grown nostalgic for them, having worn mainly dresses and trousers for the past two winters.
