The garment I chose in John Lewis was a coat designed by Ted Baker, priced at £199. Even though it was pricey, it was very elegant and had a fur neck. To make the coat slightly more casual you could remove the fur. It has a thick elasticated belt around the waist to create curves.
I paired this with a Ted Baker cross body bag, priced at £160. The items complement each other, as they are both black, and the zips and chains are all gold. The bag is leather, with a suede top panel and could be worn formally or casually.
