Every season, it's a good thing to delve into your wardrobe and remind yourself what's in there. ("Shopping your wardrobe", as Gwyneth Paltrow refers to it.) You can feel good about donating your unwanted pieces to charity, or make a quid or two selling that handbag you never used on eBay, or, you might even find things that you forgot you had that are perfect for now. Put aside a rainy Saturday afternoon to do it, and, voilà, you've been shopping without making a dent in the bank balance.
