I am normally very careful with laundry. I know what fabrics to wash and how to wash it. That does not stop a rogue shirt or dress from being washed incorrectly and shrinking.
And this Dry Clean Only dress made of 58% Wool and 42% Cotton should never see the inside of a washing machine. Since this little accident, I no longer sort out my dry cleaning from the dirty laundry. My Dry Clean Only garments now have a special bag. As soon as I get undressed, it goes directly into the bag.
I followed the instructions and soaked both garments in warm water mixed with hair conditioner (herbal essence, but I doubt that matters). After about 10 minutes, I hung the shirt and pulled & tugged to stretch it back into the correct length.
The shirt is about 3 inches longer! I wore this dress last week. It was rewashed (very gently in cold) and stayed long again. Totally fixed!
The dress required a second treatment (warmer water and a 20 minute soak) then much more tugging. The weight of the dress really helped to pull it down. The lining is a poly-blend so it kept proper shape and length throughout the shrinking and anti-shrinking treatment. After the unfortunate washing, the lining stuck out several inches longer than the shrunk dress. Now the dress and the lining are about the same length. Not a total failure, but certainly not a great success. I am going to hem the lining up about an inch so that the dress is salvageable. Mostly fixed.
