Do Polyester T-Shirts Shrink?

Polyester shirts can absolutely shrink if you don’t take proper care of them. It’s because the material is made of many small, tightly-woven threads.

If the shirt is constantly being washed in hot water and then dried on high heat, the shrinking process can be accelerated even more.
