I bought some Levi's 501s for the first time a while back. They are the button jeans compared to regular zipper jeans. Is there some kind of magic buttoning 501s when you are a urinal? I always have to undo my belt, then start with the big button, then undo each smaller button. Unless undo the belt and big button, I can't undo the smaller buttons. Do you suppose to leave the smaller upper button undone or something? They are great jeans otherwise. I've used them for about 4 of 5 months pretty regular, and still have button troubles. Anyone want to undo my buttons for me, or give me some practical advice when using the 501s at pee time? Thanks!
