Sewing is my first passion so here's what comes to my mind--
hand stitch about a 1" piece of elastic to both sides of the ribbon, making it a continuous circle. Hide it behind the bow/flower. If you wanted to make it removable, put some velcro on one side of the elastic then another piece on the ribbon. voila. You can buy sew-in or iron-in elastic. They also make a sticky kind but I don't think it would work well for this type of thing.
I haven't actually done this but it seems like a good solution to me.
