Halloween is a family affair for the Schaaf family.

Parents Carrie and Stuart Schaaf, and daughters Elizabeth, 14, and Mackenzie, 7, all celebrate the ghoulish day in costume. They've been characters from "Sesame Street," "The Wizard of Oz," "Sleeping Beauty," "Scooby Doo and the Gang" and even various food items.

This year, the Sugar Land family was inspired by the hit Disney film "Frozen."

"The girls always pick the theme," Carrie Schaaf said. "I think for them, the music (from 'Frozen') is so captivating and magical."

Schaaf created this easy, no-sew version of a gown for Elsa, one of the two princesses in "Frozen," in about an hour. "Once we worked out the details, it was easy."

Skirt

(Measurements based on size 7 girl)

7 yards of tulle, in one or more colors

1-yard package of 3/4-inch white elastic

Top

Blue tank top, camisole or sleeveless leotard

1½ yards sparkly trim for neckline and armholes

1 yard of sparkly white tulle (or substitute plain white tulle and use a glue stick to attach crystals, available at craft stores)

Tools

Scissors

Tape measure or ruler

Tacks

Board or other surface suitable for tacks

Hot-glue gun and glue sticks

To make skirt, measure princess around her waist by using the elastic. Do not pull elastic tight. Tie a knot on both ends of the elastic so the tulle will not slide off.

To determine how long to cut strips of tulle, measure princess from her waist to her ankles, then multiply measurement by two, as tulle will be folded over the elastic. To cut the tulle, spread the fabric over a large surface and cut like wrapping paper. (You may also fold layers to cut more than one strip at a time.) Each strip should be 5 inches wide and the predetermined length.

Tack both ends of elastic to board to ensure it doesn't move while tulle is being attached.

To attach tulle, take a strip and fold it in half. Make a loop at the folded end and place the loop underneath the elastic so that it sticks out several inches past elastic. Pull the long ends through loop (that sticks out of the top of the elastic) and tighten. You may have to adjust the knots as you go along so the tulle hangs straight. Alternate colors if using more than one and push the knots close together for a full skirt.

Attach tulle to entire length of elastic. Remove tacks from elastic and summon your princess. Wrap the elastic around her waist and tie it to make the skirt. Don't clip excess yet, as adjustments may be necessary.

Work the tulle knots around the skirt until satisfied with placement. Add white sparkly tulle strips over skirt, if desired. If necessary, trim tulle ends so your princess does not trip.

To make top, attach sparkly trim around neckline and armholes with hot-glue gun. For the neckline, start on back of garment so ends meet there rather than in front. For the armholes start under the arm so the ends meet there. Work in small sections since the glue dries quickly.

If using a leotard, do not glue the trim to the elastic around the neck or the armholes because it will prevent elastic from stretching, making leotard hard to put on. Attach trim to the fabric right next to elastic instead.

Summon your princess once again to determine cape size. Measure her from shoulders to feet to determine length, then measure from shoulder to shoulder for width. Add 6 or 7 inches to the width so there is enough tulle to make a knot on either side. Cut the tulle accordingly. Tie the ends of the cape to each shoulder strap across the back.

Outfit your princess and have her twirl. That's the best part.
