The 11 Best Pieces in the Reformation 30% Off Winter Sale

By Swedan MargenDecember 12, 2025

If the past few weeks have put you in the sales shopping mood, then I have great news for you. As of today, Reformation has launched its winter sale with 30% off a selection of elegant pieces—yes, that discount is even higher than Black Friday. As smart shoppers, it's not the great discount that we're focused on, but the actual pieces included. And having scrolled through every single discounted buy as soon as the sale launched, I can confirm that so many worthwhile and celebrity-approved buys are now at 30% off!

Reformation's 30% off winter sale has arrived just in time for Christmas gifting (and self-gifting) and for our 2026 wardrobe reset. The best part? It includes so many longstanding best-sellers that have proven their worth over the years, whether in the wardrobes of our own editors or celebrated by some of the chicest celebrities around. Think the Clara Cashmere Cardigan that consistently proves classic styles work hard in our wardrobes. If your denim collection is missing key styles, consider the Cynthia and Cary styles (which Jessica Alba wears above), which I've personally tried on and adore. Yes, they also come in petite lengths now, too!

Today, I'm focused on truly smart sales buys. Think perfectly tailored trousers that will bring a polished edge to dressing all year round, soft knitwear to bolster my cosy winter wardrobe, and sleek tops that will make my jeans, tailoring, and skirts feel that much more put-together. For those with weddings and parties filling up their calendars, you'll also be pleased to know that Reformation's famed dresses are also available for less, including the consistently adored Oren Silk Dress, which Raye wore recently!
