Men's attitudes and opinions affecting their purchase and use of cotton and competing fibers in selected clothing items are reported in this nationwide survey. Focus of the study are dress shirts, light-weight sport shirts and slacks, and undershorts. For six other items—pajamas, socks, undershirts, outerwear shorts, tailored sport coats, and outer jackets—inquiry was made only about ownership, purchaser, number purchased in 12 months prior to interview, and type of store in which the items were usually bought.
