The October 12, 1961 Evening Capital (Annapolis, Maryland) ran a story titled, "Disposable Clothes Seen Just Around The Corner." Excerpts appear below.
A research laboratory cuts its big laundry bill way down by sending dirty smocks, coveralls, etc., to the garbage pail. A housewife convinces her husband that her new party dress is a good bargain because she'll be able to wear it four times before throwing it away. Vacationers, ready to head home, stuff campsite trash and bedding into pillowcases and throw them into the campfire.
Disposable clothes are here - still being tested, but very much alive and kicking.
The article goes on to talk about the American public's issues with waste.
Part of the problem is one of salesmanship. Disposable clothes are still a novelty and command novelty prices. In addition, the American public is still hamstrung by the idea that waste is bad.
