Answer: Swatches of fabric.
Explanation:
A costume designer may attach swatches of fabric to costume renderings for texture and color combinations to be shown to the director.
Costumes convey information to the audience, as they help to establish their emotions, wealth and inner changes. Providing renderings that accuarately convey the fabrics, colors, proportions, and construction detail for each costume, is a key talent for costume designers.
