Know the costume size for each actor in the play. Measure the actors for costumes if necessary. Take measurements for the chest, bust, waist, hips, back, arms, neck and head. These basic measurements cover any possible costume or accessory like a hat.
Keep a record of measurements for reference. Create a file on the computer or write measurements on index cards. Refer back to the measurements when constructing costumes to ensure a quality fit.
Research clothing for the time period and setting for the theater production. If the setting is a place like the ocean or a magical forest focus on their specific environmental elements. Talk with the director for any additional guidance.
Cut out or print pictures to use as a guide for costume creation. Put the pictures in a folder or box to keep for future reference with the same time period or similar setting.
Develop the costume by building from a central piece of clothing. Use layering and creativity when adding details to costumes. Sew the costume according to measurements to achieve a tailored fit or to add minor detail. Embellish basic clothing for costumes by adding decorative details with a base stitch. Use hot glue to help secure embellishments.
Modify the clothing to create costumes. Alter the garment with fabric paint. Adhere beads, lace or upholstery rope with a base stitch to create detail for authenticity. Collect basic style clothing from thrift stores, garage sales and estate sales.
