Baptismal clothing is apparel worn by Christian proselytes (and in some Christening Outfits cases, by clergy members also) during the ceremony of baptism.

Members of the Church of Jesus Christ of Latter-day Saints dress in white clothing to perform and to undertake baptism. Traditionally, the proselyte wears a white jumpsuit, white socks and white underclothing. The person performing the ordinance wears either a white jumpsuit or white slacks and white shirt. Historically, women and girls wore white dresses with weights sewn in at the hems to prevent the clothing from floating during the ceremony.
