If you ask any fashion editor on our team where they shop for quality basics, I guarantee they're going to mention minimalist-chic retailer COS within their top three picks. As someone who has been shopping at COS for over a decade, I can personally attest to just how good COS's selection of versatile, easy-to-wear staples is. In fact, practically every in-the-know fashion person in my circle is savvy to the brand's sleek and elevated styles.
So when COS has a sale, we editors don't miss a beat when it comes to adding the best pieces to our carts, which brings me to why we're here today! Right now, COS is having an epic Friends & Family sale with up to 25% off sitewide when you use the code COSFRIEND at checkout. (Some exclusions may apply.) The sale is filled with new spring arrivals, fresh silhouettes, and elevated year-round basics that will bolster your capsule wardrobe.
Below, I'm sharing everything worth buying from the epic five-day sale. A word of advice: Don't sleep on these deals. The sale ends on March 31!
