Lightweight cardigans are perfect for pairing with spring/summer outfits. If it’s not quite chilly enough for a jacket, but you still want to have something to keep you a bit warm, wearing a cardigan is the ideal choice. Having a light sweater really comes in handy when you're dining out, in the office or at the movies where the AC is on full-blast.
Plus, they can fit into a bag or tote for easy-access!
