The BILI Jean sits between a straight leg and a flare: high on the waist, slim through the hip and to the knee, then just enough opening to change the line — a shape that lengthens the leg, especially on a heel. Soft stretch denim in Jacky Blue, a deep blue softly washed down, with light fading at the thigh — as if it already has some miles on it. With boots, obviously. But sneakers work too.
