Answer

If you are asking in the context of Jain ritual purity, puja, samayik, pratikraman, or visiting a derasar, then yes, it is generally considered best to wear clean inner clothes as well as clean outer clothes.

Explanation

In Jain practice, external cleanliness supports inner purity and respect toward:

• Arihant Bhagwan
• Siddha Bhagwan
• Guru Bhagwant
• Dev, Guru, and Dharma

So, before religious activities, one should ideally wear clothes that are:

• Clean
• Freshly washed
• Not sweaty or soiled
• Simple and respectful

This includes inner garments, because they are also part of the body’s clothing and cleanliness.

Spiritual Understanding

Changing into clean clothes is not only about physical hygiene. It also creates a feeling of reverence, discipline, and mindfulness. It helps the mind become more prepared for dharma.

Takeaway

For Jain religious activities, it is best to wear clean inner and outer clothes. If there is a specific situation, such as after bath, during puja, after using the bathroom, or before samayik, you may tell me and I can answer more specifically.
