Hi Elk......I don't know if this suggestion will help you, but you might try looking for jackets that have two-way zippers that allow you to open the jacket up from the bottom as well as from the top. Being able to open the bottom by even an inch or two can make an amazing difference in how a jacket sits on your hips.....I don't have any specific models/brands to suggest (in wool), unfortunately. Athleta has at least two or three winterish jackets that have a two-way zipper, but I think they're all fleece or other synthetic materials.....( www.athleta.com )
[Lisa, that vest is GORGEOUS! Great pick!]
