Wedding Party Clothes

I don't think it's appropriate to ask people to buy specific attire when you're not asking them to be in the wedding party.

They kind of are in the wedding party? We are having a very small wedding so we didn't want people standing with us as we get married because there would be almost no one in the audience. They will be in pictures and still be in the procession. If that makes any sense!

Unless you're asking them to be bridesmaids or groomsmen, I don't think it's appropriate to request specific attire.

I think it would be great to let people wear what they would like.

Our families are going to wear blue. I wanted my sister and his brother to wear dark blue cause they're part of the "wedding party", but everyone else will wear a version of blue. My dad already showed me his light blue shirt he'll be wearing.
