I have a very similar jacket to that and as the poster above says, they are a timeless and versatile winter staple.
Regarding your concern over the pockets, it seems to be a common trend to have them patch and flap pockets on herringbone jackets which might contribute to the boxy look, or at least the bulk at hip level. I had the flaps on mine removed for a slightly more sleek silhouette, so you might consider that.
