i noticed that you ended up building a coat above the girl's physique, but i wonder... is she wearing a shirt underneath (even if it's form-fitting)? if so, the fabric wouldn't cling to the breasts to the point where it would revert back to the sternum... there would only be a slight indentation, but then it would carry over from one breast to the next almost as far out as the bust is, and would have a slight 'stretching' of the fabric.

just curious as i think it would alter the way the overcoat would drape as well.
