I'm looking for the impossible probably - in fact don't really have an idea in my mind of what it will look like but know what it needs to do! Anyway I'm looking for a jacket which is casual but could go with smart outfits. Quite warm and waterproof but doesn't look as if I'm about to go on a 10 mile hike. Washable, and which goes with both trousers and skirts. Any ideas?
