80%wool, 20%silk. These are sooo beautiful. Thin, feels more like a heavy nylon. Wide leg measures 10 1/2" cuff opening, measured flat. Hangs straight down. Hook-eye fly closer! 33" inseam, (w/- 2" hem). 30" waist. If you know you're designer cloths you know what this is. Little snug on me. Labeled as US8 but more like a small 6. I generally wear a size 8. Worn a few times & dry cleaned after each use. No damage. Looks brand new All garments clean & well cared for.
