Now, don't let the possibility of shrinkage scare you off from buying 70 cotton 30 polyester clothes. There are a few tricks you can use to minimize the risk of shrinkage. For example, you can try pre-shrinking the fabric before you sew it into a garment, or you can use a shrink-resistant treatment to help protect the fabric.
And hey, even if your favorite shirt does shrink a little bit, it's not the end of the world. You can always try stretching it back out to its original shape, or you can just roll with it and enjoy the new, slightly-smaller fit. After all, it's just a shirt – it's not worth stressing about!
