Okay, I'm a mum, spend my life doing the school run. I'm 33 and a size 10. I live in straight leg jeans and converse. I need a coat that goes with all of that, but that wouldn't look too out of place on the rare occasion I go out. Warm and practical would be good, but a bit stylish too - in a jeans and converse kind of way, if you see what I mean. Any ideas please?
