Oh blue where are you?

I call it this sweater the miracle sweater because it seems to go with everything I own. However it is a little too big and not as warm as I would like. So I am on a mission to find a replacement. Although there a hundreds of lovely blue sweaters in the world - this color (I call it French blue which is completely unhelpful as a descriptor) is hard to find. So if you see a cardigan you think might work- let me know!
