Thus far, the fit of the pink JOR thong is just right for me - including the type of material, spandex. The Yellow thong is cotton (not my preference) and was perhaps a little too loose for me. I've always loved the black thong - and although 90% of the time that thong feels fine - it is tighter and has a string going up the back (not a wide cloth like the other two) which can be a bit torturous at times. So, for the black thong I had to be in the right mood to wear it.
