'Unveiled' in the Bible

But every woman praying or prophesying with her head unveiled dishonors her head. For it is one and the same thing as if she were shaved.

Judge for yourselves. Is it appropriate that a woman pray to God unveiled?

But we all, with unveiled face beholding as in a mirror the glory of the Lord, are transformed into the same image from glory to glory, even as from the Lord, the Spirit.
