The M&S sale has officially launched for summer 2026, and it offers a good balance between resort-ready wear and summer-in-the-city essentials. Leading the charge are breezy linen and fluid wide-leg trousers that look tailored, while still offering airy comfort when it's boiling outside. If there is one hero piece that sent fashion editors into a frenzy when it was first released, it is the faux leather weave jacket. Featuring an intricate woven texture and a rich, modern finish, it is the ultimate transitional layer to drape over summer dresses now and carry straight into autumn. From delicate camisoles to slinky slip dresses, these are pieces to snap up in the sale, because the look will still be going strong into next year.
