Many were appalled when we broke the news that kitten heels were making a comeback, but like it or not, they have become the fashion editor's shoe style of 2017. If you looked down along the front row at any fashion show in September, you would see a line of Manolo Blahnik and Dior black slingback kitten heels and mules, and now M&S has jumped on the trend and created a £30 pair that is causing a frenzy in fashion circles. These backless mules have a low, sensible heel height and a satin bow on the front and are available in an elegant black style and a more flamboyant purple floral print.
