Yes,dressing appropriately shows respect during Shraddh in Gaya.
Men: Traditionally wear a clean, white cotton dhoti. A simple kurta or angavastram (upper cloth) is acceptable. Avoid stitched lower garments like trousers or pajamas during the core rituals if possible. No leather belts or wallets should be carried.
Women: Should wear a simple saree or salwar kameez, preferably in sober colours (white, cream, yellow, pastels). Avoid black, very bright colours, and excessive jewellery. Ensure attire is modest and clean.
General: Clothes should be freshly washed. Avoid wearing anything black. Footwear is removed during the rituals. The idea is purity and simplicity while performing Shraddh in Gaya.
