That is what I would wear to Church is blue jeans,and it might be a tee-shirt too,for that is my style,and I ride my pedal bike a lot,and that is what I wear,and when I go to the gym that is what I wear,and when I eat that is what I wear,and I may go to sleep wearing that,but I do not see what is the difference between wearing blue jeans,or nice looking slacks,or a suit to Church,for I do not see how that affects our relationship with God,as long as we look presentable,and neat,and clean,and God said be in to modest apparel,not in to things expensive,so a ten dollar pair of jeans,and a 5 dollar tee-shirt,and I am good to go,because I got better things to spend my money on,and some can spend one hundred dollars on the same two items,but they are only paying for a name,and I say,you do not look any different than the cheap clothes.
Also I have come to notice that more people that deceive in a big fashion,and crooked,the majority of them seem to be wearing a suit,instead of plain clothes.
