The ANATOMICA jeans collection, 【618 JEAN'S】, boasts a beautiful silhouette reminiscent of the golden ratio (1:1.618). The 618 ORIGINAL is the model that brought together designer Pierre Fournier and Kinji Teramoto, and is a masterpiece of ANATOMICA. Inspired by US NAVY work pants, the "seamless" construction, without side seams, creates a beautiful silhouette. It's a classic yet feminine straight silhouette with a deep rise. This pair uses original left-hand twill denim fabric developed exclusively for these jeans. Left-hand twill denim is a special fabric used in 1950s American denim. It's a unique pair with specifications exclusive to ANATOMICA. I am selling these because the size didn't fit, and they've been sitting in my closet, though I received them from an acquaintance.
