Does polyester shrink?
No – polyester hardly shrinks, unless washed or ironed very hot.

How to prevent it
- Wash cool: 30 °C or as the label says, never hotter.
- Use a gentle cycle and a lower spin.
- Dry without heat – on a line or flat; the dryer is the main culprit.
- Iron at the temperature on the label.
If it has shrunk
- If it has shrunk: soak in lukewarm water with hair conditioner for 30 minutes, gently stretch and dry flat. It helps some fabrics; felted wool won't recover.
