Sweats are great for Power Ranger or Ninja costumes, too. Pick your favorite superhero color and add felt accessories as needed. Buy one of those dangling paper skeleton decorations at a party supply store, cut it into pieces and affix them to the front of your child's black sweat suit for a skeleton costume. A yellow sweat suit layered with a red T-shirt -- and a little stuffing -- makes an adorable Pooh.
Leotards Complete The Look
Some costumes just wouldn't look right made from a sweat suit. Who ever heard of a ballerina in sweats? For some of those ideas an inexpensive leotard works wonders. For an easy ballerina, buy several yards of pink or white tulle at your local fabric store (it's quite inexpensive) and a couple of yards of a matching two-inch-wide ribbon. Choose the length you want the tulle skirt to be and make the width two times your child's waist measurement. Measure your child's waist, mark off that amount in the center of your piece of ribbon and hand gather the tulle as you hot glue it into the space you measured off (start in the middle and work toward each end). The trailing pieces of ribbon are used to tie the skirt in the back. Add glue-on rhinestones, tiny silk flowers, or little dots of glittery fabric paint for an extra sparkle.
Another costume that works well with leotards is a butterfly. Use a pastel leotard and several large squares of pastel gauze or gauze scarves. Pin one corner of the scarf to the back neck of the leotard and fix the diagonal corner near the wrist. Add more scarves pinning each one lower down the back.
