grey one is 65% polyester/35% rayon, but don't worry it doesn't wrinkle; and the brown one is 99% wool/1% lycra spandex with a lining of 100% polyester says to dry clean, but I've been washing it with cold water and no problems, not too much wrinkling at all enough to iron. The brown one is listed as a petite with stretch, but I'm 5'5" and the brown one fit at the knee; the grey one fits me below the knee.
