Like the sequin shift dress, Sienna's ultra-mini skirt has that vintage quality she's most known for. Team with a T-shirt, jumper or blazer for three entirely different looks, all to be worn on repeat for day or night. The Art Deco-influenced design is carefully crafted with a concealed side zip and fully lined to hang impeccably. M&S X SIENNA MILLER Womens M&S X SIENNA MILLER Sequin Mini Skirt
