DaasYochid, while there are standards of tznius that aren’t a “free for all” whether an individual woman follows them are her choice. She should, but we don’t stone them, throw bleach on them, beat them or kill them if they don’t. If you don’t want to marry them, invite them into your home, be friends with them, that’s fine.
