The Sunday Best
What's the Sunday best? Nothing but formal wears. I am not Cristian. But I know a lot of people go to church on Sunday. It is inappropriate for us to wear too rugged clothes as we go to church. It is a good idea to wear suits, ties and/or dresses as we go to church. This is why some people use "the Sunday best" to imply the formal wearing.
If you are a businessman, you will have a lot of time to wear formal wears such as suits and ties. On the basis of this fact, some people use "business attire" to mean the good dressing.
