Levi Strauss Signature GoldWomen's Modern Bootcut Jeans (Also Available in Plus)

WTF does waterless mean?

Anyone have issues with the buttons coming undone?

Is the waist band very stretchy? I have a health condition and the waist cannot be tight. However, my legs are slim and I love a boot cut

I am in between sizes, and carry most of my weight in my mid section. Should I size up or down?
