I recently heard (I’m not sure if this is 100% correct, and i dont have a source for it) if a girl is in a place where there are only goyim (meaning- no jewish men) she does not have to be 100 percent tznius.
For example, if she is on a far off beach where there are NO jewish men, its ok for her to wear short sleaves, shorter skirt, no socks etc.
Just wondering if anyone else heard of this, and if theres a source
