Ahemm............! As to attire, the assumption would be that God is expecting Western (no, not cowboy) civ type clothing. Yet, from what we know from the Bible, He would seem to prefer folks in their birthday suits (pun intended) vis a vis Adam and Eve. (I think He gets a kick out of the naughty bits.)
OTOH, what we know from Hollywood is that He (God, not Cecil B. de Mille) is quite comfortable with robes and such. I think if it were a smiting matter, God would make it abundantly more clear what he wants us to wear. Therefore, on all matters where He is not abundantly clear, we can assume that it is a "matter of personal conscience."
Does anyone in their right mind think the the Almighty gives a fig what we wear?
Well, if you went around naked in public you might get arrested. So apparently some prefer that you do not walk around naked. In some places it is allowed, like on a beach or some other secluded area. The human body is work of divine creation it does not bring God shame.
If you wore a revealing dress to a place of worship it might cause a brother that is weak in the flesh anxiety. If a man that was married looked at you in a lustful sort of way, this would cause problems with his wife if she caught him looking at you. Proper dress in modesty is admonished sound in reason and in excercising a clean conscience before God. This should take the lead in deciding what to wear. Mr. E
