This weekend Sienna Miller enjoyed the heatwave in a classic British summertime outfit — until you take a look down at her feet, that is. She wore a blue and white striped T-shirt with cropped kick flare jeans, a yellow tote bag by Frame and a pair of wayfarers, but then she wore a very un-Sienna Miller pair of sandals. She wore a pair of red fluffy with two straps and a chunky buckle. These fluffy sandals might be a little out-there, but furry sliders are having a moment as the likes of UGG and Prada have furry sandals.
