M&S Slashes Price of Top-Rated Blazer to £25 in Smart Sale
M&S blazer reduced to £25, perfect for capsule wardrobe

Shoppers seeking a timeless wardrobe essential have been presented with a significant opportunity, as Marks & Spencer has dramatically reduced the price of one of its most popular blazers.

A Wardrobe Workhorse at a Fraction of the Price

The retailer's Slim Single Breasted Blazer, which normally retails for £49.50, is now available for just £24.75. This represents a saving of 50% and brings the cost of a well-tailored piece under the £25 mark. The offer was highlighted on 3 December 2025, making it a prime find for winter shoppers.

Designed as a versatile foundation for a capsule wardrobe, the blazer is praised for its ability to elevate both casual and formal outfits instantly. It is crafted from a fabric with added stretch, promising a comfortable fit that doesn't sacrifice a smart, structured silhouette.

Design Details and Styling Versatility

The blazer features classic notched lapels and a sleek single-button fastening for a clean finish. Practical front welt pockets add a touch of sharp detailing. Available in both black and dark navy, the piece comes in petite and regular lengths to help customers achieve a better fit.

Its design makes it suitable for year-round wear. The lightweight construction is ideal for spring and autumn, while the structured cut allows it to be layered over knitwear during colder months. For styling, it can be thrown over a t-shirt and jeans for weekend polish, paired with tailored trousers for the office, or used to smarten up a slip dress for evening wear.

Customer Reviews and Stock Alert

The blazer holds a 4.5-star rating on the M&S website, with many customers endorsing its versatility. One reviewer called it a "plain single-breasted blazer suitable for year-round wear, neat and smart." Another stated, "A great jacket. Nicely tailored enough to be both for a formal event and for casual dress."

However, prospective buyers should act quickly. The black colour option is already selling out fast, with several sizes reported as out of stock. This indicates the deal is proving popular with savvy shoppers looking to invest in affordable, high-quality tailoring.

While the M&S blazer offers outstanding value, the market for versatile blazers remains broad. For those seeking alternative options, retailers like All Saints and ASOS also offer their own takes on this classic garment, though at significantly higher price points.
