I used to never wear a shirt and tie to church...I did that all week at work. I wore (still do) dress pants and a button down...if Sunday is a day of rest,that is one way I do.

I occassionally wear a suit/sport coat...but only when I'm scheduled to be an usher. I'm not opposed to dressing up...I just need new suits to kill the memory of a job I was blessed to have for 2 years (but hated).
