When it comes to shopping for dresses, there are a few brands I regularly rely upon. I trust Reformation to cater to my fuller bust, Other Stories to deliver pretty options to suit my budget and Ghost to create the easiest throw-ons to elevate my daily wares. These are a few of the labels I love and make a beeline for whenever I'm looking to up my dress game. However, recently, I've found that many of the best dresses I see on social media come from another store: Marks and Spencer.

If you're an avidBest Knockoff Luxury Clothing UK reader, then you'll know our editors have a serious soft spot for M&S. From its lingerie to its cashmere, its jeans to its various clothing collections, the high-street hot spot never lets us down when we need a sartorial pick-me-up or a basics refresh. And right now, Marks and Spencer is serving up some of the best dresses that work for this transitional time, as we head into the last days of the summer season.

Deputy editor Maxine Eggernberger wears a white M&S dress with caped broderie sleeves. She is looking into the distance in front of green bushes in a recent image.

This was my favourite summer dress for 2023, and I found it at M&S. Now I'm looking for something as reliable for 2025!

I'm keen to update my dress roster right now and, naturally, I've turned to M&S to pinpoint its best new-in styles. So, let's turn our attention to the dresses that truly impressed me. Some tap into my penchant for neutral tones, while others, well, I was surprised at just how much I loved them. Scroll on to read my honest reviews of the best Marks Spencer dresses to buy now.
