Sienna Miller's 'beautiful' M&S faux fur jacket has shoppers buying two

Fashion icon Sienna Miller has once more collaborated with M&S, and her eagerly anticipated second clothing collection is already winning over style enthusiasts. Following the rapid sell-out of her initial range this summer, her new offering for the festive season includes everything from dazzling sequin mini dresses for parties to edge animal print waistcoats and accessories that add an on-trend touch to any look.

Yet, it's this sumptuous faux fur black jacket that steals the spotlight. The piece is a masterpiece of fashion featuring a bold shawl collar and lavish elongated fur, melding classic Hollywood allure with a slice of rock 'n' roll bravado, reports OK!.

This coat is the ideal throw-on to elevate a winter look instantly and is surprisingly easy to style up or down. Pair it with classic black heels, a silky cami top, and leather trousers for a glam-rock look, or wear it over a fitted jumper, wide-leg trousers, and heeled boots for a daytime outfit.

Although recently released, M&S patrons have swiftly embraced the jacket, bestowing upon it a 4.8-star rating. A particularly passionate customer exclaimed: "This is the most beautiful jacket. Every time I wear it, people comment. It is stylish and feels like a warm hug. It is so gorgeous I have bought two. Greedy, I know, but I couldn't bear to be without one in my life! I love it (in case you haven't realised)."

Another customer expressed their satisfaction: "I'm delighted with this jacket, which I plan to wear with a dress for the Christmas season and with my palazzo jeans for a less formal but elevated look." They continued: "I'm a size 8-10. I ordered size 8, and it's perfect. The slightly cropped length suits my petite frame."

A different shopper shared their experience: "I wore this jacket for the first time last night with jeans. It is so soft and warm, and I received many compliments. I was in two minds, but I am glad I bought it. The fit is great. I love the fact that it is short to the waist, plus it is very stylish."

Adding to the positive reviews, another buyer remarked: "(I) love this jacket, (it) can be worn casually with jeans, trainers or dressed up. I usually wear size 10 M&S tops but bought size eight as I wanted a less bulky look."

However, they did note a minor concern: "The only thing I'm concerned about is the slight shedding of the garment when I tried it on. I'm hoping it won't continue while I'm wearing it."

Still, this gorgeous number will make a great statement piece in any wardrobe. You can shop the faux fur black jacket for £79 via M&S — and see the entire Sienna Miller collection here.

If you're looking for something slightly more affordable, New Look's iteration is strikingly similar and costs £59.99. If you prefer a shorter, boxy fit, this Next £62 jacket might be worth a look.
