The 27 Best COS and Reformation Items to Buy for Fall 2025

It’s not every day that you scroll through new arrivals and find great stuff. Trust me, I shop all day, every day (it is my job, after all), and most of the time, I’m lucky to find a handful of share-worthy deliveries. Today was one of those rare times, though, when I opened dozens of tabs to save pieces for later use. The brands responsible? COS and Reformation, two retailers that were competing for my attention all day.

At Ref, satin dresses and pants dominated, but not the kind you’re probably picturing. The satin in these cases is heavy-duty, not flowy, with an elegant structure to it that makes any form it takes look expensive. Thick cashmere and wool sweaters for fall also arrived this week, each one more tempting than the next. At COS, the winning continued, with suede handbags and sneakers coming second only to outerwear, which ranged from barn coats to funnel-neck trenches. My shopping cart, as I’m sure you’ve already guessed, is filled to the brim, and I can’t bear the idea of cutting a single item inside it. My guess? You’ll have the same predicament.
