Gold is an obvious investment and this Mulberry Mabel bag, £876 from Net-A-Porter, is a seriously blingly investment item, if you can afford to splash the cash. Gold, silver or bronze handbags never go out of fashion and are ideal for this time of the year and the height of summer, to really lift an outfit. Earlier this year, I bought this J for Jasper Conran gold leather bag for £38. I've only just started using it, as it really lifts an outfit in the gloomy wet and cold weather. It will also be ideal for trips out in summer too, with vintage summer dresses.
