For a traditional corsage, a bow is often added at the bottom of the corsage. I've already added in a few loops scattered throughout the bow, so the is the finishing touch.
Keep the loops smaller, usually no bigger than a two finger width.
After making the bow, twist the bow loops by slipping in two fingers and twisting hard. This separates the loops apart and makes them stand up better. Wired or filament edged ribbon holds a bow shape better than a soft double satin ribbon with no support.
I tuck the bow up under the bottom flower heads, snuggling it up tightly against the bottom. Tape into place with florist tape.
If you want to add in some interesting texture, florists sometimes pull the petals off flowers and use only the colored center for emphasis.
