It helps a litte but not completely. Women may be the same size and measurements, but a completely different shape (men have this problem too, right?) What we need is technology that can 3D scan an item and virtually drape it. Then I can get myself scanned and try on the virtual draping. Only then will I fully be comfortable spending real, non-returnable money on the internet for clothes (shoes and accessories are less of a big deal for fit).
