My office is right round the corner from Topshop at Oxford Circus, which means the "just popping in to take a quick look" lunchtime visits are pretty frequent. Fortunately for my wallet, this blue and black gingham short sleeve t-dress, with it's relaxed, slouchy drop waist, was in the mid-season sale down to £15.
Further down Oxford Street, Marks and Spencer also tempted me with this sharp shoulder bag in sleek pebble leather. I like its boxy, Sophie Hulme-ish shape, gold twist lock and good stop-packing-the-kitchen-sink size. I need more of those sizes.
