And if it wasn't already a tricky enough look to pull off, this season it's all about head-to-toe white ensembles. So steer clear from the red wine, and, well any foodstuff if you want to remain stain-free. Ketchup down the front isn't the look we're going for.

If you hadn't already noticed, this spring is all about the hidriff (it's like the midriff, but, er, higher). It's the only piece of flesh to flash. Wear your skirt high on the waist, and your top cropped on the ribs, and you're good to go.
