It is a multimedia learning system that provides fundamental underpinning knowledge on the manufacture of apparel. Apparel designers, also called clothing or fashion designers, conceptualize and create items of clothing. They often specialize in one type of design, such as casual, evening or active wear. Common duties include tracking current fashion trends and predicting future ones, sketching new designs, selecting patterns and fabrics to use in garments and overseeing production. They may then show items to creative directors, clients or retailers, depending on if the garments are to be custom designed or mass produced.
