Sellier vs Retourné
Hermès's two constructions: stitched outward, or turned and hidden.
Christie's explains that in Sellier construction the leather edges are stitched outward, leaving the stitching visible and giving crisp angles, while a Retourné bag is stitched and turned inside out, hiding the seams and giving softer, rounded edges. PurseBlog adds that the Sellier Kelly has cost more than the Retourné, a gap that has generally hovered around $1,000.
