The Marks and Spencer Uniform Sale 2026 typically drops in July—just before the back-to-school panic sets in. But online, it often sneaks up early, so keep an eye on their website starting in June. Sign up for their newsletter if you’re really keen, because they’ll send you a “sneak peek” code for an extra 10% off. Yes, please.
In-store, look for the big red signs that say “SALE” with a smiley person on them. And don’t be shy—grab a basket and go wild. The staff are usually lovely and will help you find sizes, even if you’re holding up a queue.
