I have bought this - www.debenhams.com/webapp/wcs/stores/servlet/product_10001_10001_64051_1189339_-1
I tried it out in the torrential downpour that caught me on the way to the bus stop today and it's
(1) Waterproof (but not shiny)
(2) Very warm (padded but not puffy) AND
(3) (I think) Stylish - it has a cinched waist so doesn't look too chunky and a lovely fluffy hood
Very happy!
