511 Slim Dark Indigo Think of this modern slim with room to move as not-so-skinny skinny jeans. (If you want the style, but not the feeling, this is a great alternative.) With a streamlined fit that’s narrow through the seat and thigh, the 511™ Slim is perfectly calibrated to look good with everything—without looking like you’re trying too hard. How are they so comfortable? Stretch denim, made with sustainable TENCEL™™ Lyocell fibers.
