When I use to make samples, or hand-make short runs of orders of lingerie that shops had placed; the one thing that always slowed me down was the attachment of the bows. To start with I hand sewed them all on, to gain the neatness i required; as I didn't have an industrial bar tacker (a machine that stitches side to side in the same place to secure bows).
I tried to practise with putting my domestic machine on a zigzag and going slowly back and forth, but it just resulted in a messy attachment with zigzag stitching on the bow and on the lingerie.
And then.... one day whilst sewing a button on, I had the idea - could I put a bow underneath the foot for it to be held in place for me to sew. Result. Treating the bow like a button, place it under the button foot with the bow secure under the prongs. Place so the stitch will go over the centre of the bow, and with the stitch on zigzag, it forms a stitch without the bow or garment moving.
