Garment prototypes: Before you actually produce garments that will be sold, you must test prototypes of each garment design characteristic. This testing helps to ensure that you have designed a garment that will comply with the standards when it is mass-produced. Seam types and trim that will actually be used in the garments must be tested. Most sleeve and neckline bindings/rib cuffs do not have to be tested. Test three samples, five specimens each, of the longest seam type, three samples of each different seam type 10 inches or longer, and three samples of each type of trim.
