I need a lightweight coat or jacket to wear if going out in an evening. I've a denim jacket that looks OK with dresses but nothing to wear with jeans or trousers. I don't suit a short boxy jacket as it makes me look big as it ends at my wide hips. Something that ends below the hips would be better. But a blazer is too smart for my needs and all else I see is utility style jackets with big pockets. Am I missing an option?
