GEMYSEWomen's Mountain Waterproof Ski Jacket Windproof Fleece Outdoor Winter Coat with Hood

Is the color of this windproof jacket the same as in the picture?

I bought a similar coat last year, Its quite heavy after a while. Would you consider this coat to be lightweight

What size should I get for a size 12? Small or Medium?

I brought a xxl as reviews said comes smaller had to send it back as it was huge on me im usually a 18 and the large fits perfect go by the size chart
