What to wear at no notice? The answer to this question is almost always going to be 'something black'. By 'no notice' I'm talking about occasions for which you've had an outfit in mind, and therefore not left much time to get ready in. And then--horror! At the last minute you discover that the crucial garment is in the laundry basket or the ironing pile, and your beloved is already standing at the bottom of the stairs calling 'Are you nearly ready?' in that helpful way which instantly solves all clothing crises.
You then dash to your wardrobe, biting back tears of rage, and snatch the nearest black dress. Next you rummage through the monstrous tangle of hosiery which is your tights drawer for a pair with no ladders. These you tug on, hopping round the room, whilst bellowing 'I'M JUST COMING!' to the solicitous enquiries from downstairs. On goes the dress. Off comes the dress. On goes the dress again, right way out. A burst of angry churning about in jewellery box locates some big silver jewellery. Squirt of expensive signature scent. Jam feet in black shoes. Prod hair. Snatch nearest brightly coloured pashmina, clomp downstairs. Compose self. Off to concert.
The great blessing is that you have had no leisure to be assailed by the conviction you look fat. I recommend it. Just make sure your skirt isn't tucked into your knickers, that's all.
