My situation is the same to you. I just want to share my ideas with you. First, I always wear a slim jean, then with a loose long sweater. It must be longer enough to cover my hips. It let me look slim. Second, using a big bag like <strong><a title="Hermes" href="http://www.shophermes.co/">Hermes</a></
strong>
to cover this problem. Third, I think a green coat(it must be a long coat) with a black panty-hose is perfect match. Oh, don't forger to wear your ankle boot. It's powerful.
Hope my answer can be helpful.
