If you're interested in trying this trend, we're loving the Heratige washed silk crops from Banana Republic ($86.50). They have a trim line whereas other cargos create extra bulk around the thighs (and not the cool, exaggerated kind either). The pockets and roll make them casual, but they're tailored enough for a night out or even work.
Prefer bows to buttons? Banana Republic offers a girlier version of the silk crop in the bag-waist short ($69.50). Both versions are available in cream or moss.
