Honestly Joy, when someone's first post on the forum is simply a question with seven words in it, I think people just don't put the time into giving long answers because they don't know if you'll ever be back to read them! I'll answer more clearly.
I come from a fundamentalist Christian upbringing. Were taught a great deal from a young age the makings of the perfect wife. I suppose in your faith than your saying less focus is put on this picture of the ideal wife?
"Our faith" is Christianity. That is all. We come from all sorts of different denominational backgrounds, we are not a single unified denomination or "cult" or anything like that. We're just a bunch of Christians from all parts of the wider Church, who happen to have seen that God does not condemn polygamy - but retain differing views on everything else! As you have a Christian upbringing, the picture of "the perfect wife" that you have been raised with is probably quite similar to the views of most of us (I'm guessing here because you haven't explained what you have been taught, there could be some peculiarities in that if you've had an unusually restrictive upbringing, but the basic ideas of Godliness, submissiveness, modesty, hard working, loving etc will be similar).
But everybody is different. There is not a single "perfect wife" mould that we'd like every woman to be twisted to conform to. Women are not objects, they are people. Everybody is different, and God made those differences because He wanted them. A husband's role is to help his wife to become the woman that God would have her be - and that is different for every woman. But it will always involve the encouragement of certain basic characteristics.
Specifically for polygamous marriage, characteristics of Godliness, faith, submissiveness, generosity, love etc will be even more important than in monogamy to achieve a successful marriage, and jealousy will be destructive.
