There's nothing like bad packing to scupper a well-planned holiday. Fortunately Sarah Walters, founder of style-passport is on hand to give us her top tips for packing for any holiday eventuality. This week...how to pack for a city break. According to Sarah, it's time to banish that knackered old backpack and grotty old trainers. "It's time to spruce up a bit. Sightseeing requires comfort but not at the expense of looking stylish." The first thing you need is: a great piece of carry-on luggage on wheels. "This should come at the top of the list. Basically a great case is a shortcut to great packing. Compartments for bottles and brushes, flaps for jewellery, zipped compartments for travel documents and reading material and then always remember to put the heavy stuff in the bottom surrounded by scarves etc. Everything else gets 'rolled' on top for a crease free arrival."
