I am looking into getting an Inverness cape. I am wondering, how important are they when it comes to cooler weather and wearing a kilt? Would normal long coats or raincoats look ridiculous with a kilt? I have a very nice wool long coat that my wife got me last year. But would it look bad with my kilt this coming fall and winter?

I guess I'm trying to justify to myself spending that much money (almost a thousand ) on a cape.
