A child's first communion ceremony is a very important part of their development in Christianity, and a proud moment for parents. The young girls will be wearing white dresses, and the boys will be wearing suits or tuxedos. The ceremony will take place in a church, and the parents need to dress accordingly. Although the parent isn't the one on display, it's important to set a good example and to respect the ceremony taking place before God.
Hygiene
Parents should be showered or bathed for the ceremony. This is a formal occasion and cleanliness is appreciated. Teeth should be brushed, deodorant or perfumes should be applied, and nails and hair should be cleaned and styled.
Attire for Mothers
Women should wear a pair of dress slacks, a dress or a skirt -- formal khaki pants are acceptable. The skirt or slacks should be paired with a blouse or blazer. The shirt should not be revealing or inappropriate in any way. Dress shoes with a pair of nylons or stockings should be worn on the feet. Tasteful jewelry can be used to accessorize.
Attire for Fathers
Men should wear a pair of dress slacks or suit pants. Khaki pants that aren't cargo-style are acceptable. A nice sweater, collared shirt or suit jacket is appropriate on top. A suit and tie is very acceptable, but not necessary. Clean dress shoes with matching dress socks should be worn on the feet. No hats should be worn in the church.
Exceptions
If there is medical condition or temporary reason why you are unable to dress accordingly, do your best to compensate. Black nylon exercise pants will go over casts and braces, or a baggy pair of khakis. People with feet issues can wear black or brown tennis shoes if unable to put feet into dress shoes. If coats are inappropriate, hang them at the door on your way in. Try your best to make due with the clothing you have to look suitable on this important day.
