I have been buying a knitted fabric at Joanns that works for ribbing. It's about $10/yd so I always use a cpn. I comes in many colors and different width ribs. They have some on the mark down rack too but that is very bright colors. I've never seen it at our WM either. Maybe a totally different stretch fabric then add detail to the shirt, if you have to, pocket, stripes on sleeves. Looks like the sleeves might be kind of long, maybe you could shorten them and add a stripe of the alternate fabric.
