My Barney's had a decent collection of RO stuff yesterday. There was a simply luscious jacket with the thinnest, most floaty leather, it seemed as soft and light as an old flannel shirt. Just beautiful. I assume this is the S/S weight leather. The jacket was lined in what I think was a silk crepe though. This was a turnoff for me because it would just be so delicate. What are most SS jackets lined with?
