What's the best waterproof/walking jacket I can buy that isn't totally frumpy?
Ideally something that's long enough to cover my bum, is properly weatherproof but comfy and not all plasticky/feels like I'm wrapped in umbrella fabric.
Bonus points if it can can be worn on top of a baby carrier without making me look like Quasimodo.
I'd like to spend less than £100 but budget can stretch if that's totally unrealistic.
