I bought these at a store and for me, they fit perfectly.  They are close-fitting, but that is why they are called "perfectly shaping".  Loose jeans wouldn't be called that, in my opinion.  I like the lower waist and the way they look on me.  I bought the size I normally wear in Levi's.  In my experience, all brands fit differently, so one might have a different size in one maker's jeans than another's.
