Have the bride put on the dress so the bustle can be completed.
Mark the center of the back of the skirt with a pin.
Measure the spots for two to four pins (depending on the length of your train) in equal distance from each other on the waistline and from either side of the center pin. These are the spots you will attach the buttons to hold up the bustle.
Lift the skirt to the center until the hem at the back is the same length as the front. Pin the middle of the skirt to the center pin and remove the dress.
Put the dress back on to make sure the pins are level.
Sew the buttons to your marked points at the waistline.
Sew small loops of ribbon to the bustle points.
Try on the dress to verify the bustle is straight.
