Please could I have some suggestions for a winter wardrobe. I am neither stylish nor beautiful. 
I'm late 40s, tall, inverted triangle, slightly overweight. I need casual clothes, but have a tendency towards scruffiness, which I'm trying to avoid. I have clothes for autumn, which I'm happy with, but don't really know what to wear when it gets colder.
I have trainers and flat black knee-high boots. I have winter coats. I used to wear skinny jeans but they really don't suit me. I've bought some boot cut jeans, but I feel like a throwback to the 90s in them. I prefer trousers to skirts
Following a pretty rubbish year (ill-health, divorce) I need to feel better about myself so please could I have some suggestions.
