So the Pinterest confession thread made me wonder what you guys did that is technically against etiquette.
I revoked previously invited plus ones (TRUE plus ones) and didn't mail anything when we cancelled our wedding. I enlisted my brother to call everyone.
ETA: I want you to know that only my sister and my best friend were effected by taking away their plus ones and they weren't planning on bringing anyone to the original wedding anyway. But I did tell them no plus ones when we rescheduled.
