Modesty doesn’t win Gods favor. If modesty alone impressed God then Muslims in burkas would no doubt be Gods favorites.
Galations 5:19Now the works of the flesh are evident: sexual immorality, impurity, sensuality, 20idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions,divisions, 21envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.
Notice the first 3 works of the flesh are Sexual Immorality, Impurity, Sensuality.. Clearly flesh has a problem with these issues and for a woman to tempt a man with a short skirt and a tight shirt is a grave sin. Generally speaking most of these 3 sins start with a woman who is not properly covered up, a woman who is not shamefaced. This passage of scripture also talks about how Sensuality is a sin, I have certainly seen some very sensuous hairstyles. Big, windblown bedroom looking hair...hair that is sensual.
Matt 5:28But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. Notice the *with her* in this scripture. She is not innocent but is part of the adultery when she puts herself in a place that causes a man to lust after her.
