put my collar on backwards

Many, many years ago, collars were not attached to a man's shirt. They were an item that had to be fastened separately. It was easy to put them on backwards if you were not paying attention.

I am old enough to have had shirts with detached collars. I occasionally put the collar on 'back to front' rather than 'backwards', though the meaning is clearly the same.

Thank you a lot, can you mean that figuratevely also to change profession for example as a doctor has ( uniform with this collar that way?)

Thank a lot, there are some profession which have also the collar that way?

could this mean also figuratevelly ... I did a misteak?

A priest has a collar that looks like it is on backwards. That is often used to refer to priesthood. In fact, that's the first thing I thought of when I read your title.

thank you a lot for your help , it should be that. jj

As Enoon said, we often say that a priest has his collar on backwards.

So I was wondering whether or not this could sometimes be a sarcastic or playful comment.

Tom: Oh, you're wearing your collar on backwards today, ar
