Fashion: Squeak and cheerful

when the weather is murky and the days are dingy, we could all do with a friendly smile – which could be why fashion with a face is having such a moment, with sales of these Marc by Marc Jacobs mouse shoes rocketing at my-wardrobe.com, following on from Charlotte Olympia's cat-faced velveteen wedge boots last season. Jacobs' mice are veterans on the footwear scene these days, but this season come in gold glitter. What better way to put a smile on your face – and on your weary feet as well? £220, my-wardrobe.com
