As a DJ, I have no idea how to bustle a dress. I do know you’ll likely be fumbling around with it while your bridal party waits to be introduced into the reception.
I would suggest having a specific person who practices the bustle beforehand. This may sound silly, but I’ll often see the mom, Maid of Honor, and an aunt struggling to do this.
Also, have a planned time to do it. You may have a DJ who’s not aware your dress needs bustled. I wish I knew this on my wedding day. The DJ announced our first dance, and my wife’s dress wasn’t bustled yet. She did her best to dance with me, but it wasn’t the easiest.
