Gloria Vanderbuilt review: Amanda jeans

Something needs to be done about the back seam for many jeans. I say many of this is not the first time I have had a pair if the ananda stretch jeans that the back seam does not line up in the center of my behind. All the pulling and tugging to scoot the seam over only helps to a degree.
This is not okay. Also I gave had a couple pair that stretch by zipper in groin area, they pucker and stretch out after just a few wears. For the most part the ananda jeans are great, but some are not inspected well. That needs to change as these jeans are not free.
Thank you
