In the LDS church, there is no christening of babies (baptism is saved until the child is at least 8 years old), but rather a simple blessing of the child by those holding the proper authority to do so. Still, there is a family celebration, and usually the baby wears special white get-up.
Unless of course the baby girl being blessed has an overly-talented Grandmother who made her blessing dress for her, and opted to not do white.
My Grandma Kitchens made this dress for me and I was blessed in it as a baby.
Then my sister was blessed in it.
Now my daughter will be blessed in it.
There is not an ounce of me that would change a thing about this beautiful dress.
