Jennifer is typically a size 6 and can wear a medium in these, but prefers the large for length.  Even in the large pant, Jennifer has to wear sandals due to her longer legs.  Brittany is typically a size 4 and prefers the small in the pants.  These pants have a true waist tie, so you can adjust them to your preferred size.  The waist tie also has the sweetest beaded fringe detail on the end for a little bit of added sass!
