That is a personal choice you should discuss with your church. They are not the same thing.
you should wear a helment toprotect you from getting any kinds of brain damage.
loose clothes and guests wear casual clothing or religious. It is worth noting that Muslims do not baptize their own children and would only go to a Baptism if their friends or family were getting baptized.
Generally one wears white for Baptism. If the religion does not do a total immersion, a suit for a boy and a dress for a girl. If there is total immersion, check with the pastor for suggestions. (White becomes see-through when wet.)
Since your baptism is a special occasion, you should wear something special. This is to say your clothing should reflect the specialness of the occasion. "Sunday Best" is probably a phrase that has no meaning anymore, but there was a time when "Sunday Best" meant "Wear a suit, or sport coat with shirt and tie" (whatever that equivalent would be for a women) But I think that is a good indicator of what you should wear for your baptism if you have the women's equivalent of a suit, shirt, and tie, etc. If not, then I would wear the nicest thing you have next to that. In short---this is not the place to wear a baseball cap, jeans and a t-shirt. That is what I am trying to say.
it doesn't it is a human tradition.
You should wear anything that help you be safe of the paint getting on your skin.
Muslims don't get baptized, so there is nothing set that a Muslim would wear to undergo this process.
Some people wear robes today in believer's baptism, but very commonly, and as in the early church, many people wear regular clothes. Preferably, clothes should be those that easily can get wet and be restored when dry.
You can wear jewelry while getting a tattoo. I wear lots of it and have 14 tattoos and have never taken off one piece of jewelry while getting a tattoo.
Peter said to be baptized in the name of the Lord Jesus Christ. you should be baptized in the name of Jesus because the spirit is the power the of God it's not a person. The spirit is a counselor.(john 14...)
