Where in any religious text is the verse "COME AS YOU ARE"?

For some time, I’ve been told that we don’t have to dress in our Sunday Best to church because some verse in the Bible states ”Come As You Are.”

I haven’t had any luck finding it. Maybe it’s in a book of the Catholic Bible that wasn’t included in the mainstream variety.

Or regardless, what verse indicates that wearing our “Sunday Best” isn’t absolutely necessary when coming to church? (Maybe it isn’t worded verbatim as “Come As You Are,” but synonymizes something to that effect.)

(Moreover, I haven’t been exactly fond of dressing up for a job interview that I won’t go to that day.)
