WHITE STUFF WOMENS JUMPER
The Katie Jumper is the kind of piece that becomes an instant favourite — easy to reach for, impossible to take off. Knitted in a rich blend of organic cotton and extrafine merino wool, it's wonderfully soft against the skin with just the right amount of warmth for the cooler months ahead.
A classic crew neck silhouette in a deep, grounding dark brown tone, it works effortlessly over everything from wide-leg trousers to your favourite jeans. Simple, timeless, and made to last.
