Looks like a new color in the Star Runner Pullover. I think it's a Soot Light stripe but could it be Pique? Probably not Pique, although it does look like it has texture to it that is different from RULU.
There is a new Lululemon video on RULU, and in that video quite a few shots of the Star Runner Pullover in Cornflower Blue. I haven't seen many store photos of the Star Runner in this colorway.
