Sorry I have been MIA lately. It's that time of the semester, and with teaching 7 courses, I never know if I'm coming or going!
We ordered STDs this weekend. Here is the sample from online.

But, here is my question. We are looking at invites. Our wedding is going to be a pretty formal affair. We believe that the invite sets the tone for the wedding. We both go by nicknames. We used the nickname on our STDs. When it comes to the invite, we will obviously be using our given names. We found an invite that we could actually use both names on it (the top names would be nicknames). Will this look too informal? Here is a picture of it.
