[General] put on a white sheet = repent in public

[vil]

Dear teachers,

Would you be kind enough to tell me whether I am right with my interpretation of the expression in bold in the following sentence?

I don’t see why I should stand in a white sheet for something I didn’t do.

put (stand) on a white sheet = repent in public

Thank you for your efforts.

Regards,

Never heard that expression but sounds reasonable.
