I haven’t lost as much as you, but I can understand a little. Your post encouraged me to try on a pair of hosiery I’ve kept locked away in a dry, cool and dark place for a while. At first, they fit just fine, but I quickly got fat and they became uncomfortably snug.
Well! They now fit just fine and are super comfortable! In fact, ordered 10 more and the beauty shop says they haven’t change the sizing or anything.
