Rag & Bone's tuxedo stripe skinny

Rag & Bone's super skinny slim fit takes on some color-blocking this spring, with contrasting tuxedo stripes. The white with blue, iris with orange and khaki with black versions jump out, while the black with grey stripe pair are a bit more sellable. From the photos, it looks like the stripe is some sort of pigment and not actually a fabric blocking or insert.
