"When I see a person (who's not homeless or hopelessly poor) wearing jeans to churches, weddings, funerals, etc., I see a very selfish person who respects no one, not even themselves."
What happens when you see a person wearing jeans to church who IS "homeless", or "hopelessly poor"? Since you can spot selfish people so well, you might want to ask those well-dressed people in church to go without their new Sunday clothes, and instead, perhaps they could give the money they would have spent on their "outfit" to these hopelessly, homeless poor people. IYIYIYI!
We have a section of the church (like a large walk in closet) which is filled full of dress clothes (for men and women) in various sizes for people who want to dress more appropriately for church but can't afford to do so.
