Showing God Respect

Scripture says: "worship the Lord in holy attire.", Psalm 96:8. God is certainly very pleased when we come to worship him at church on Saturdays or Sundays. But I think it shows a lack of respect when we come to worship dressed in sneakers, jeans, sweatshirts and sweatpants. When we come to dine with Jesus, it's certainly "fine dining". If we "dress up" to go to a fine dining restaurant, shouldn't we do the same when we come to dine with Jesus?
