Your jeans are wreaking havoc in your life.

They spark feuds with your sister (she keeps borrowing yours), fights with your boyfriend (you keep borrowing his), and a fracas or two with your mom (she inexplicably finds the low-waisted look “trashy”).

Sounds like you could use some new relations. Kasil, a flattering new line of denim, will ease tensions on all fronts.

Kasil’s Devious design fits like a femme version of your boyfriend’s jeans, so you won’t have to steal his. They ride slightly higher in the rear, protecting you from the peekaboo-panty look your mother hates so much. And there are plenty more styles and sizes to go around (we love the Karen, a good-butt jean with a boot-cut leg and super-cute back pockets, and the Zoe, a trouser jean with medium rise), so your sister can get her own pair. Meaning you can resume diplomatic relations with all three.

Wow. What’s next — world peace?

Available at Jolie Joli, 1623 North Damen Avenue, at North Avenue (773-342-7272). To see styles, go to kasiljean.com.
