Denim on Denim

What is the rule again for wearing denim on denim? Oh wait, there isn't because it is on point and trendy with a mix of casual. The thing about this look is you could really go any direction. Put some heels on, you got a night outfit. Want to make it so you can run errands - add the sneaks and cap and you are off to Target. You want to mix same color denim and make it a jumper-esque, BE MY GUEST! Or you feel like doing denim of all sorts of shades, that works too. It is a win win situation for everyone.
