You can't get it back just by dry cleaning. You have to take it to the dry cleaner and have it dry-cleaned. After washing, they will iron it. Just tell them the ironing time and ask them to enlarge your clothes. It's actually quite simple. They washed your clothes, and it won't shrink. You should have found them such clothes. Then the dry cleaners must tell them to dry clean and be responsible for losing money.

There is another way. If you have an iron at home, two people can pull clothes evenly. Don't push too hard. Just iron the clothes with an iron and you will be back in a few minutes, but be careful not only to pull up and down, but also to pull. Otherwise, you will feel that the clothes are thinner.
