Cubix Cotton Colorblock Sweater

I am a stickler for 100% colorblock flattering items. This is it, but it's too big for me now. This is thick cotton that holds its shape and fits slightly cropped and tailored. The color is very unusual. It has a black roll back mock turtleneck and the color is a cross between yellow and green, but more to the olive green side. I purchased at upscale boutique. GUC right out of dry cleaner. Never machine washed.
