I would stay, but one of the reasons I became Orthodox is because I think we preach that Christ can meet any of us in any state we're in. Can you imagine Christ demanding that the Samaritan woman put on a more modest outfit? No. He gently leads her back to God's love, and that's the starting point for any changes in her life based on her free will to love Him back. Modesty starts on the inside.
That being said, I do wish that in America women weren't discouraged from wearing more modest clothing. I don't mean bouffants and pinafores like in that cult, just, you know, not belly revealing jeans and exposed bra straps and stuff. Even a pregnant lady has trouble looking modest these days.
