I want it for taking the dc to school, so that even if I've got old jeans on I still look smart. We live in the country, and school involves a lot of mud getting in and out of the car, and I often have to carry my toddler who may/may not have muddy boots. I have a very warm wax cotton dog walking coat with a lining, and a lovely Timothy Foxx fitted jacket, and a full length cashmere/wool camel coat, so I need something in between. It needs to be fitted as I am fairly hourglass (a bit chumpy at the mo) and not black. I want to spend no more than about £150. Am I wishing for something that doesn't exist. Oh, and it needs to be warm! 
Tia.
