The men in our church rarely wear ties or suits. Most often you can find the men in dress slacks or nice jeans, paired with collared shirts.
The ladies in our church dress mostly in business casual. Occasionally some will wear a dress or skirt, but mostly dress pants are the norm.
The children dress in what is comfortable for them, however we do encourage modesty in them, by not wearing shorts that are too short or shirts that are too revealing. Most of the teens wear jeans and tennis shoes.
