No need to feel blue with this River Island collection of knitwear. From classic jumpers to on-trend cardigans, you'll find your ideal shade (and that extra layer of warmth) in our edit of women's blue knitwear. Heading for a dressy lunch with your girlfriends in less than ideal weather? Embrace a new take on the nice-top-with-jeans look and pair a form-fitting knitted number with some chunky ankle boots. Or, layer up with a crisp white shirt underneath an oversized jumper for a tailored look with a modern twist. It's easy to stay warm and fashion-forward with a blue knit dress: simply throw a blazer on top for office chic, then add white trainers and a cross-body bag when 5pm rolls around. Blue knitwear isn't just for the colder weather either: a pastel blue top tucked into flared jeans makes an easy-to-wear outfit for a springtime stroll.
