You can't always rely on our weather to stay warm (or dry) – and that's where River Island's edit of summer jackets for women comes in. You'll find women's lightweight summer jackets to throw on over your dress for alfresco evening drinks, as well as leather-look pieces to wear with just about everything. We've also got longline kimonos, tailored blazers and printed duster coats to complete your going-out ensembles. Heading to an outdoor gig? Take one of our oversized shackets and pair it with some shorts and chunky ankle boots before braving the unpredictable elements. There are plenty of waterproof options in our range of women's summer jackets, too. Just roll one up and pop it into your bag in case of rain.
