I have been looking for a pair of jeans that would fit tightly on my flat rear. These jeans do the trick. They fit beautifully. As a matter of fact I am ordering another pair.
These jeans are really nice, except they do run small. I would suggest ordering at least one size larger than you normally wear.
I ordered these in my normal size 4 and couldn't even close the zipper or button the top. At the same time I had purchased two other pair of casual pants in the same size and they will fit perfectly after they are washed and shrink a little. I would suggest ordering a larger size or two.
