Nylon chiffon petticoats are used a lot for square dancers but a longer version can be used for bridal gowns. They make the skirt full and when twirling look very nice. These can be very expensive to purchase but can be made without a lot of materials and very inexpensively. Even the most inexperienced seamstress can make a nylon chiffon petticoat.
Using five yards of nylon chiffon, sew a basting stitch (a long, running stitch) along the top of the material.
Measure the waist of the person the petticoat is for and add two inches to that measurement.
Draw up the basting stitch until the material measures three times the person's waist measurement in step 2.
Fold the nylon chiffon in thirds width-wise.
Stitch the seam where the nylon meets on the length side of the material to within 5 inches of the waist.
Cut the elastic to the person's waist measurement in step 2.
Cut the ribbon to the person's waist measurement in step 2 adding ten inches.
Sew the ribbon to the waist of the nylon chiffon leaving five inches on each end of the waist.
Fold the ribbon over and sew it to the waist of the nylon chiffon creating a pocket to insert the elastic.
Insert the elastic into the ribbon and sew the ends together.
Place petticoat on the person and tie the ends of the ribbon together when wearing.
Another version of this would be to sew the petticoat directly to the skirt waistband.
