I was first introduced to Forever new when I worked in the lingerie department of a store that eventually became part of Macy's. One of the manufacturer's reps explained to the team how it really is the best for anything with elastic in it (bras, panties, shapewear, hosiery) because the formula does not cause the elastic to become brittle or degrade as ordinary detergents tend to do. I tried some and found out she was right! I really think my quality nylons and compression hose do not develop runs as fast as when I was using Woolite. My bras stay in great shape throughout their expected lifespan. I was so disappointed when Macy's and other similar stores stopped carrying it. I was very much relieved to find I can order direct online. I now know from my own long experience who right that manufacturer's rep was.
