Halocho is covering knees, elbows, neckline (to whatever degree your Rav holds necessary). After that, it’s all subjective. Sure, women can wear clothes that conform with the letter of halocho and are nevertheless totally inappropriate, but that cannot be defined in any real way. So using terms such as long hanging hair or wobbly high heels is not particularly helpful to the discussion. You are attempting to define the indefinable, and, however hard you try, that just isn’t going to happen.
Halacha also includes Tova’as B’shuk / Vered. See Kesubos 72B. We all agree that there is no one answer as per what that includes, but we can also agree that it means dressing like a Zona. What a Zona dresses like can be up for discussion.
