I have just come accross a novel way to update your shoe collection: shoelery! Onceuponabelt.com stocks a wide selection of studded and fringed additions for footwear, my favourites being the antique dangling chains and the ankle feathers. They don't come cheap though; at £75 and £45 respectively. For a cheaper alternative, try H&M for chain necklaces or head down to your nearest haberdashers and make your own.
