We worked in a large Christian organization and they would not allow open-toed shoes. Someone has a warped view of what is "sexy".
They also had rule about our college gals NOT wearing button up blouses (gaps?) and not wearing anything necklace longer than a choker, since it accentuates the female form. Of course gals had to wear culottes and hose too, or they were not "spiritual".
Patent-leather shoes have also been forbidden by some, because when a lady stands up, the shoes may reflect her underwear. Hey, you can't make this stuff up.
I would have never thought of the peeping ability gained with patent leather shoes, nor would I imagine the length of a necklace chain as being immodest.
Were there any similar restrictions on men's clothing?
