Womens American Eagle size 8 long but fit like a 6 long Black Jean

Womens American Eagle size 8 long but fit like a 6 long Black Jean I've purchased these same jeans for years for work they fit small so these are a 8 long but fit like a 6 long. I've put on weight the past few months so be sure to checkout the rest of my closet for Women's size 6 items.
