Colour-wise, you should be honing in on grapes, violets and lilacs, along with greys and petrol blues. Maxmara has some of the prettiest purple hues: again, a classic label whose clothes will last and last. And if you haven't already bought a trench coat, then do, because the belted-up look will linger long through autumn. Enough of being bossy, though. The sales are a time to experiment, and my best advice is to buy what you like.
