In Jainism, pratikraman is an important spiritual practice involving repentance, reflection, and seeking forgiveness. The ideal attire for pratikraman is clean, simple, and modest clothing. Traditionally, Jains are encouraged to wear white clothes, as white symbolizes purity and simplicity, which are conducive to spiritual activities.

A pooja dress—if it is clean, simple, and modest—can be worn during pratikraman. The essential point is that the clothes should not be ostentatious or distracting, and they should be clean. The focus should be on inner purity and sincerity, not on outward appearance.

In summary: Yes, you can do pratikraman in pooja dress, provided it is clean, simple, and appropriate for spiritual practice, as per Jain traditions.
