casual and hoor are not mutually exclusive. casual does not mean slob and hoor does not mean someone in a dinner gown and makeup and jewelry. so the terminologies are incorrect.
so moving away from terminologies, and getting to the core of your question, i think u are saying, why do some guys dress like slobs yet expect their wives to be dress up, well those guys need a swift kick in the dingdongs. or better yet, the wife asking him to dress better, or helping him dress better.
Now typically I have seen these complaints from desi stay at home wives who would dress up in the evenings while the husband who has been in a monkey suit all day at work just wants to be in something more comfortable, not to say that nice looking clothes cant be comfy. either way if the wife helps the dude figure stuff out it would be good.
now as far as people relocating, it does not happen just because of marriage but even after marriage for career reasons. If the person moving needs extra support and is not getting it perhaps the sane approach would be to just talk.
lastly, when ladies talk about husbands not being supportive 'enough' in such matters, you have to realize that they did not come fully programmed and dont often know what is needed by the other person, and their own lives have seen major changes as well that they are dealing with.
key = communication
Ok, yeah i agree wrong terminology.... you can be dressed casual but still look neat and presentable.
What do you do when you are not even a wife. I mean you are introduced to a guy and he comes out/sends a pic in a very casual/somewhat sloppy attire but you have been told 10k good things about him.
