Blue, glorious blue – it's a magical hue. And with blue co-ords, you can enjoy top-to-bottom colour. From bright turquoise to deep navy, it never fails to make us feel amazing. We've got flared trousers, longline blazers and knitted tops sharing this versatile colour palette, so it's easy to find smart and casual outfits alike. You'll spot all the usual River Island flourishes too, like tassel ties, ruffle hems and ruched sides. In warm weather, choose a blue co-ord set with a cropped top and mini skirt for a breezy feel. For a retro look, why not double up on denim with a jacket and jeans? After a busy day, slip into a blue matching set of satin pyjamas for a silky-soft texture against your skin as you snooze.
