Sleeveless Stripe Front with Bow. Use old white t-shirt to make the "sleeve" part on the girl scout shirt. That will allow a wider sleeve area and a bow. Just match it with an earlier post on my sewing board.
Flower rosettes from t-shirts -- Cut a strip of t-shirt fabric, stitch lengthwise down the center of the strip, gather, fold in half lengthwise, and roll it up. Glob a bunch of glue on the back and stick it on a circle of fabric.
