In case you haven't noticed, the Black Friday fashion deals have officially begun—and with it comes a wave of chic deals that feel almost impossible to ignore. Still, if you’re being sensible (as I’m attempting to be), it’s worth setting a strict budget to keep the excitement from turning into chaos. For me, a £300 limit is the perfect sweet spot: focused enough to avoid impulse buys, but generous enough to secure timeless, high-quality pieces I’ll genuinely wear for years—plus a few French-inspired staples I can’t resist. And the three high-street brands I know will deliver exactly that? COS, Mango and Reformation.

Each one offers something distinct. COS remains my go-to for elevated wardrobe foundations—from sleek merino basics like the best-selling Merino Wool Top to the cult-favourite Arch Tapered Jeans every chic fashion editor seems to own. Mango is unmatched for outerwear and tailoring, consistently producing floor-skimming wool coats and sharply cut trousers that look far more expensive than their price tags. And then there’s Reformation, the rare unicorn blending sustainability with exceptional design. Its Clara Cashmere Cardigan is a bestseller for good reason, while pieces like the Gale Satin Trousers bring a refined elegance to evening dressing.

Below, I’ve curated the chicest Black Friday finds from COS, Mango and Reformation—pieces that fit my £300 budget, elevate a winter wardrobe instantly and align with that understated, French-leaning aesthetic I return to year after year.
