Let's also remember that the church is the house of God. Why is that restaurants, night clubs, operas, casinos, etc have dress codes? We can argue and say I can wear anything I want to the opera or to a particular restaurant, etc. But chances are, some places won't even let you in the door if you don't have the right dress code. So too then, there is a dress code for church. If we show respect for these other places that ask for dress codes and abide by their wants, then we too should hold enough respect for the house of God. The Bible clearly states how a woman or man should dress, in modesty, not the outward adorning, etc. And it does clearly state that a woman should have her head covered when praying or prophesying. I went to Italy years ago, and I was on a tour of the Cathedrals in Italy. The man at the entrance of the Cathedral was handing out paper skirts and tops to women. He said women could not enter this particular cathedral if they were wearing shorts, pants, or sleeveless tops. Many of the catholics put a shawl or veil on their head before walking in as well. I am not catholic, but I am just saying that they are upholding the dress code in many places over there.
