Who knew Sienna Miller's new M&S collection would top our winter wardrobe wishlist...
Here are the three outfits we will be buying before they sell out


As we step into the festive season, M&S has brought us the ultimate gift—a glamorous collection designed in collaboration with none other than Sienna Miller. This second collection has just arrived in time for the party season ahead, and this feels like the perfect way to make an entrance this winter.
M&S is truly earning it's reputation as one of the best British clothing brands. This collection offers everything we love about the festive period—elegance, boldness, and a touch of sparkle. With 35 standout pieces that perfectly capture Miller's iconic vintage style, these pieces are simply dreamy, and ideal if you're on the hunt for the best Christmas party outfits. Whether you're planning on going bold this festive period with vibrant shades or sequins or you're channelling a more refined feel with black lace and tailoring, this collection is the place to shop.
A standout feature of the collection is that it directly draws from Sienna's personal style archive. Each piece truly feels personal to Miller, making it even more exciting that we get to shop her iconic looks for high-street prices. With silver sequins reminiscent of David Bowie's Ziggy Stardust, a faux fur jacket with buckles inspired by Miller's punky pirate boots from the early 2000s, and much more. Here are our favourite 9 pieces, or directly shop the collection here.
