1. Bend the trouser leg into a normal shape, clamp it with a clamp, then soak it in warm water, and take it out to dry after 30 minutes.

2. Put the trouser legs flat and iron them flat. Be careful that the temperature is not too high to avoid scalding the fabric.

Turn the trouser legs over and iron the inside.

4. Use a professional trouser leg shaper to shape the trouser legs.
