I used to have a lovely 1970s black dress. If it wasn't a Gunne Sax, it looked like one. Made of black crinkle cotton with black cotton lace trim, it had a square neckline and a flounce at the hem. It was a bit long--everything was--so I hemmed up the flounce about six inches, which brought it up to my ankle.
I wore it a lot. It was flattering, washable and just all sorts of awesome. After a while, it began to look a little rusty, so I re-dyed it. Chandra wore it for Halloween in 1989, when she was Scarlett O'Hara In Mourning. I do have a picture of that, somewhere, so I shall have to scan it into the computer.
Eventually, styles changed, and I had nowhere to wear it after SSS and I split up, so I donated it to Goodwill.
Years later, shopping at a different Goodwill, I was perusing a huge round rack of such dresses, and came across it. I was a bit taken aback, thinking it was an identical dress, but when I examined the inside (like you do) I realized that a) it had been dyed and b) the hem was definitely my work.
So I bought it.
It's probably not still around, but I was thinking about it a few days ago.
Because it was awesome, and I bought it twice.
