The No-Sew Princess Costume is a classic for a reason! Many little girls never tire of a princess pretend games, making this a great Halloween costume. You can make this princess dress in under an hour using a few no-sew tricks. Don't let these instructions stress you out! You're basically making a tube of fabric with elastic. You can do it!
Iron the fabric to remove excess wrinkles and creases. Open up the fabric and lay with right side down. You should have a rectangular piece of fabric with two raw edges and two finished edges. Fold over one raw edge about 1-inch and iron to crease. After fabric is creased, iron a piece of fusible fabric webbing tape under the crease and fuse fabric according to package instructions. This is the hem of the dress.
With fabric still right side down, fold the other raw edge over about 2-inches and iron to crease (this will be the edge opposite the hem). Use your hot glue gun to glue just the very edge of the 2-inch fold, leaving a casing. You will run the elastic through this casing later, so be sure to leave an unglued area wide enough to eventually feed through a safety pin and the elastic.
Lay fabric out flat with right side up. Fold in half so that the plain edges meet. Hot glue the two plain edges together to form the back seam. You should now have a tube of fabric with the hem at the bottom, the casing at the top, and a seam at the back. The dress will be inside-out.
Leave dress inside out for now. Flatten the dress so the seam is in the middle back. Cut a 24-inch piece from your ribbon. Fold the ribbon in half to find the middle. Hot glue the very middle of the 24-inch piece of ribbon to the front-center of the dress (over the casing) so it forms a V. This will be a halter strap to keep the dress from falling down.
Turn dress right side-out. Flatten dress so seam is in the middle back. Take your remaining piece of ribbon (about 12-inches depending on your child's size) and fold it in half to find the middle of the ribbon. About 6-inches down from the top of the dress, squirt a 4-inch line of hot glue horizontally on front of dress, and attach the center of the ribbon to the line of hot glue. This will fix the ribbon waist ties to the dress.
Use the measuring tape to measure around your child's chest right at the armpits. Add 2-inches and cut a length of 1/4-inch elastic using that measurement. Attach a safety pin to the end of the elastic, and thread through the casing at the top of the tube.
When the elastic is threaded completely through the casing, tie ends of elastic together.
To wear the dress, the elasticized top will be pulled up to the armpits. Tie the neck ribbon around the back of the neck halter-style. Take the long waistband ribbons and criss-cross them around the body as many times as you can and tie at the back or the front.
