I am catholic and in our church i mean you really see both dress up and casual dress....times have changed to be honest with you and it really doesnt matter the dress. most people will dress up but i mean you dont HAVE to. When i went and attended a bapstist church for a class i had to take, it seems the same way, but its more a "custom" to dress up nice at a baptist church i guess?

i mean honestly i think its just how you were raised in your family and how tradition has passed down in your family.

dressup and going to church is much like a comparison as catholics like to drink and the majority of baptists don't especially at weddings (atleast thats how it used to be)
