Definitely needs an under layer then this becomes a beautiful, gossamer, unique sweater that works with equally well with dress slacks or casual jeans. It is certainly an eye catcher. Excellent quality and lovely open weave. I bought the Copper and its a gorgeous color. I am thinking about other colors.
I love the pattern on this type of sweater in general, but have been so happy with the colors/workmanship that I will definitely buy another until I have all 4 colors! Especially happy with the blue-it is a unique shade between aqua and a dusty blue...
