This is all excellent news !!!
Mine is only a minor victory, seemingly, compared to these. My rope-like undies are now starting to slip, and I have bought some "decent" underwear - it never seemed worthwhile for so long.
And, I gingerly tried on a nice pair of cord jeans from 3 winters ago, very doubtful I could wear them out last week, and the zip came straight up, and I felt so good.
