I have owned Levi's 512's in the past and loved them so I didn't have any concerns when ordering these. Because of the many reviews that said they were smaller than the size indicated I ordered up one size from what I normally wear. Should have ordered two sizes up. These run very small and as one reviewer said you instantly have muffin top. They are uncomfortable from the thigh up, makes you feel like you are squeezed into a sausage casing. The material is not the same as the previous 512's I have ordered either. It is thin and flimsy feeling. I don't think they'll hold up. I wanted true denim but these feel like stretch pants. I really thought based on the ones I already owned that I couldn't go wrong but I was. So disappointed. It's hard enough to find jeans that fit well and then to have them changed completely was a huge let down.  The only plus I can give these is that the length is perfect for my 5'1" frame. Maybe I can find the old version of 512s somewhere else. If the Levi Company is reading this I say don't mess with a good thing. Give us back our jeans!
