I Tried On COS's New Autumn 2025 Collection—These Stylish Items Earned My Endorsement.

      Welcome to The Great Try-On. With autumn fully upon us, we seized the chance to try on some fantastic new arrivals from your favorite brands, capturing the experience along the way. We believe that the best way to shop online is by seeing items in real life and reading honest reviews, so we hope this journey helps you make your most successful purchases of the year. During my trek across central London to try on COS’s autumn 2025 collection amidst heavy rain and a Tube strike, I couldn’t shake the feeling of Emily Blunt’s character in The Devil Wears Prada sarcastically reminding herself of her love for the job. It was only when I escaped the downpour and entered the warming Coal Drops Yard boutique that I truly connected with that sentiment.

      As a fashion writer, it’s both an honor and a thrill to build a career around visiting changing rooms, testing new seasonal pieces, and being at the forefront of fashion trends. So when I felt a bit irritated about facing unpleasant weather for the sake of style, all it took was being surrounded by the store’s calm white walls and racks filled with desirable pieces to remind me of my good fortune. My upbeat mood was further enhanced as I quickly moved through the store, picking up item after item that I was eager to try on (while sticking to the brand’s seven-item limit per dresser, of course).

      Indeed, that’s the magic of great clothing. There is already much discussion about the mood-lifting effects of fashion—it's known as dopamine dressing for a reason—but I won’t dwell on that here. Instead, what’s worth discussing is the quality and exceptional design of the high-street favorite's latest collection. The London-based brand has been a staple in the UK fashion scene since its founding. Recently, COS has made efforts to tap into a different market: the US. My visit coincided with the retailer’s latest presentation at New York Fashion Week, so the store was brimming with styles showcased on the runway, lending them an air of sophistication and metropolitan flair.

      These elements have always been a part of COS's designs, which is why discerning shoppers typically turn to them for impeccable tailoring and luxurious knitwear. It’s true that COS shines brightest during the colder months, and I would argue that this season’s collection is one of their strongest yet. Therefore, it was quite a challenge to condense everything I saw and tried into a concise selection. While you’ll only find a small yet thoughtful selection of the new arrivals that caught my eye here, both in-store and online have a plethora of styles worth exploring.

      For context, I’m 5’5” and typically wear a size 8 to 10. My personal style combines ‘90s minimalism, preppy aesthetics, and playful elements, leading me to enjoy wearing classic wardrobe staples presented in unique ways. The items I tried on reflected this, from the burgundy pony hair trainers that revitalized a simple silhouette to the checkered shirt exuding both grunge and sophistication. I’m confident you will also appreciate the pieces that caught my attention. So, without further delay, keep scrolling for my top picks from my COS autumn 2025 try-on.

      **The Best COS Buys for Autumn 2025, Tried and Reviewed by an Editor:**

      1. **Cashmere Cardigan + Triangle Scarf + Wool Trousers + Pony Hair Trainers**

      **My Review:** Here’s a little-known fact—the high street is where most fashion aficionados shop for knitwear. With many brands offering cashmere at more affordable prices, these textured pieces often rival those found in designer collections. COS consistently provides stunning cashmere items in various styles and colors. This merlot-hued cardigan is a perfect example; it's labeled as brown but appears as a deep plum in person, aligning well with autumn 2025's color trends. The brushed texture resembles the alpaca hair cardigans that have been gaining popularity, yet the goat’s wool makes the style much softer compared to other natural fibers. I chose a size M for a more relaxed fit, but you can easily size down for a snugger shape to pair with the slouchy pleated pants I styled it with.

      Anyone who knows me understands I can be quite particular about wool trousers. (If they're good enough for the Olsen Twins, they're good enough for me!) I can be that way because I rarely wear denim jeans and often find linen styles cumbersome. These trousers had a great weight and structure. As their name implies, they’re both relaxed and fluid while maintaining shape as they flow down the body. They’re labeled as wide-leg but don’t flare in a way that makes me feel like I'm wearing bell-bottoms or give me an inverted triangle appearance.

      Finally, I completed the look with the matching triangle scarf and minimalist pony-hair trainers. This is the kind of outfit I adore for autumn—simple, elegant, yet incredibly cozy.
