Levi's 504 'low slouch straight' jeans

Now HERE is a fantastic pair of jeans! Dark wash Levi's 504's. Straight leg. I was very distressed to get home and find these didn't quite fit me. I've not actually met a pair of Levi's with this particular look and funky little details like the slash belt loops or the bright red button hole. Size 5; is that an American thing? Measurements in photos. A fantastic pair of Levi's that is a little bit different!
