I'd sew it into a lightweight vintage 70s style coat. The knit would be interesting to fashion into a coat, and would give some challenges to solving how to best line/underline/interface a knit. The coat would be comfortable with the stretch. Under the coat, I'd wear a navy outfit for the office with a few flashes of neutral colors in a silk scarf and a great bag. I've wanted for a long time a watch with strap that wraps and wraps around your wrist. Here I'd wear it over the navy sleeve.
I would love this coat in this fabric. I wouldn't want to take it off indoors!
