I thought this Matty M cardigan would be 'lightweight,' so I was surprised (thought not unhappily so) that this cardigan is actual sweater weight, more for Fall/Winter. The navy color is VERY dark, almost black. After reading size reviews, I figured I'd order a Medium (being a U.S. W's size Medium/8/10) I could have easily gotten by with a Small and still had some "wiggle room." Overall, it was worth the purchase, and I'm pleased with the sturdy quality. I may consider purchasing another color in the Fall.
